Discussion 6
Threat and Hazard Identification and Risk Assessment
A. The 5 Ws of THIRA
In the previous chapter, we discussed the virtues of hazard assessment and impact
analysis. We also presented a simple method for addressing natural and manmade
hazards within an agency or small community. The purpose of this short chapter is to
introduce the reader to a much more thorough process used in the United States for
assessing hazards, projecting capabilities needed to counter those hazards, and
performing gap analysis. The process, which originates from the U.S. Department of
Homeland Security (DHS) and the Federal Emergency Management Agency (FEMA) is
called the Threat and Hazard Identification and Risk Assessment (THIRA).
Precisely, the Threat and Hazard Identification and Risk Assessment (THIRA)
process serves as a vital framework encompassing four key steps. Through these steps,
emergency managers meticulously evaluate their community's most significant hazards
and threats, discerning their potential impacts in relation to a multitude of factors. The
THIRA process commences with the comprehensive identification of hazards and threats
facing the community. This step involves a meticulous examination of historical data,
expert assessments, and situational analysis to compile a comprehensive inventory of
potential risks. These may include natural disasters such as hurricanes, earthquakes,
floods, and wildfires, as well as human-induced hazards like industrial accidents, terrorist
attacks, cyber threats, and pandemics.
Once hazards and threats are identified, the next step entails estimating their
potential impacts. This involves assessing how each hazard or threat may vary in its
severity and magnitude, considering factors such as population density, infrastructure
vulnerabilities, environmental conditions, socioeconomic factors, and the presence of
critical assets or facilities. By understanding the nuances of each hazard's potential
impact, emergency managers can better prioritize preparedness efforts and allocate
resources effectively. With a clear understanding of potential hazards and their impacts,
the THIRA process shifts focus to evaluating vulnerabilities and capabilities. This step
involves identifying the community's vulnerabilities—weaknesses or deficiencies that
may exacerbate the impact of hazards—and assessing existing capabilities—resources,
assets, and systems that can be mobilized to mitigate risks and respond effectively. By
conducting this assessment, emergency managers gain insights into areas requiring
improvement and opportunities for enhancing resilience.
Armed with insights gleaned from the previous steps, the final phase of the
THIRA process involves the development of mitigation and preparedness strategies. This
entails formulating targeted interventions aimed at reducing vulnerabilities, enhancing
capabilities, and mitigating the impact of identified hazards and threats. Strategies may
include infrastructure improvements, land-use planning, public awareness campaigns,
training and exercises, emergency response plans, and coordination mechanisms. By
implementing these strategies, communities can enhance their resilience and readiness to
confront a wide range of potential disasters and emergencies. In essence, the THIRA
process empowers emergency managers to systematically evaluate hazards and threats,
understand their potential impacts, assess vulnerabilities and capabilities, and develop
targeted strategies to enhance resilience. By leveraging this four-step framework,
communities can better prepare for and mitigate the impacts of disasters and
emergencies, ultimately safeguarding lives, property, and livelihoods.
Indeed, the process of conducting the State Preparedness Report (SPR) based on
capability targets derived from the Threat and Hazard Identification and Risk Assessment
(THIRA) serves as a crucial mechanism for emergency management programs to
enhance their readiness and resilience. By scrutinizing their current capabilities against
the established capability targets, emergency management programs gain invaluable
insights into the gaps and deficiencies in their preparedness efforts. These gaps highlight
areas where essential resources, such as personnel, equipment, training, or coordination
mechanisms, may be lacking or insufficient to meet the demands of potential disasters
and emergencies. Armed with this knowledge, emergency management programs can
begin taking proactive steps to address these shortfalls. This may involve strategic
resource allocation to prioritize investments in critical areas, such as enhancing training
programs, acquiring necessary equipment, or improving coordination and communication
protocols. Additionally, it may entail the development and implementation of targeted
action plans aimed at closing identified gaps and strengthening overall preparedness
capabilities.
Moreover, the SPR process fosters a culture of continuous improvement within
emergency management programs, encouraging them to regularly assess and reassess
their readiness in light of evolving threats and changing circumstances. By periodically
revisiting capability targets and conducting subsequent SPR assessments, programs can
track their progress over time, measure the impact of their preparedness initiatives, and
adapt their strategies accordingly. In essence, the SPR process serves as a catalyst for
action, empowering emergency management programs to proactively identify and
address gaps in their preparedness efforts. By establishing capability targets, recognizing
resource shortfalls, and taking concrete steps to bridge those gaps, programs can enhance
their readiness and resilience, ultimately better positioning themselves to protect lives,
safeguard property, and ensure the well-being of their communities in the face of
disasters and emergencies.
The four-step process for developing a THIRA is identify the threats and hazards
of concern. Based on a combination of experience, forecasting, subject matter expertise,
and other available resources, identify a list of the threats and hazards of primary concern
to the community, give the threats and hazards context. Describe the threats and hazards
of concern, showing how they may affect the community, establish capability targets.
Assess each threat and hazard in context to develop a specific capability target for each
core capability identified in the National Preparedness Goal.
Other jurisdictions, such as local units of government and regional planning
groups, are highly encouraged, but not required, to complete a THIRA in conjunction
with the SAA. The SAA is expected to engage the whole community, including tribal
nations, to ensure that the entire scope of statewide risk is incorporated into a state’s
THIRA. The primary goal of THIRA is to help community planners understand the risks
that confront them. Through the THIRA process, communities identify and prioritize
their hazards and threats and then make better decisions about managing the associated
risks. They do so through better planning and the development of needed core capabilities
and mitigation strategies. The latter is more the focus of this textbook.
At the culmination of the meticulous and rigorous Threat and Hazard
Identification and Risk Assessment (THIRA) process emerges a critical artifact: the set of
capability targets. These targets serve as the North Star guiding preparedness efforts,
providing a clear and structured framework for states to assess and enhance their
resilience to disasters and emergencies. The state preparedness report (SPR) assumes the
role of the lens through which current capabilities are scrutinized against these
established targets. It serves as a comprehensive assessment tool, enabling states to gauge
their readiness across a myriad of domains, including planning, training, exercises,
equipment, personnel, and coordination mechanisms.
As states embark on the SPR assessment, they meticulously evaluate their
preparedness posture against each capability target, seeking to identify areas of strength
as well as vulnerabilities. Through this process, states document any gaps that exist
between their current capabilities and the desired state outlined by the capability targets.
These gaps serve as crucial signposts, illuminating areas where additional attention,
resources, and investments may be warranted to bolster preparedness efforts. Whether it
be deficiencies in planning, gaps in training and exercises, shortcomings in equipment
and resources, or lapses in coordination and communication, the SPR serves as a
roadmap for states to prioritize actions and initiatives aimed at addressing these critical
gaps.
Moreover, the SPR assessment fosters a culture of accountability and
transparency, as states are required to report their findings and progress to federal
agencies, stakeholders, and the public. This open and collaborative approach to
preparedness planning enables states to leverage the collective wisdom and expertise of a
diverse array of stakeholders, fostering a shared understanding of risks and priorities and
facilitating the alignment of resources and efforts. Ultimately, the SPR assessment serves
as a catalyst for action, empowering states to take concrete steps to enhance their
resilience and preparedness in the face of a dynamic and ever-evolving threat landscape.
By leveraging the capability targets generated through the THIRA process and diligently
documenting gaps and areas for improvement, states can chart a course toward greater
resilience, ensuring the safety, security, and well-being of their residents in the face of
disasters and emergencies.
Embedded within the intricate tapestry of emergency management, the capability
targets derived from the Threat and Hazard Identification and Risk Assessment (THIRA)
process assume a central role in shaping the State Preparedness Report (SPR) assessment.
These capability targets, meticulously crafted to align with the most pressing risks and
vulnerabilities identified through THIRA, serve as the yardstick against which states
measure their preparedness posture and resilience.
The SPR assessment, conducted on an annual basis as mandated by the Post-
Katrina Emergency Management Reform Act of 2006 (PKEMRA), leverages the
capability targets as its foundational framework. Each capability target encapsulates a
specific aspect of emergency preparedness, spanning a diverse range of domains,
including planning, training, exercises, equipment, personnel, and coordination
mechanisms. During the SPR assessment process, states evaluate their performance and
progress in meeting each capability target, providing a comprehensive overview of their
preparedness efforts across various dimensions. This assessment serves as a critical tool
for identifying strengths, weaknesses, and areas for improvement, guiding strategic
decision-making and resource allocation to enhance overall readiness and resilience.
By anchoring the SPR assessment in the capability targets generated through
THIRA, states ensure alignment between their preparedness priorities and the evolving
threat landscape. This approach fosters a culture of evidence-based decision-making,
enabling states to prioritize resources and investments in areas that offer the greatest
potential for enhancing their ability to manage emergencies and disasters effectively.
Furthermore, the iterative nature of the SPR assessment process allows states to track
progress over time, identify trends, and measure the impact of preparedness initiatives.
This continuous cycle of assessment, feedback, and improvement facilitates a dynamic
and adaptive approach to emergency management, positioning states to better anticipate,
respond to, and recover from the myriad challenges posed by disasters and emergencies.
Enacted in the wake of the catastrophic Hurricane Katrina, the Post-Katrina
Emergency Management Reform Act of 2006 (PKEMRA) stands as a pivotal piece of
legislation aimed at bolstering the nation's emergency management capabilities and
enhancing its resilience to disasters. Among its key provisions is the requirement for
states to maintain a current State Preparedness Report (SPR) on file with the Federal
Emergency Management Agency (FEMA) as a prerequisite for receiving federal
preparedness assistance administered by the Department of Homeland Security (DHS).
The SPR serves as a comprehensive assessment of a state's preparedness posture,
encompassing a wide range of factors, including planning, training, exercises,
capabilities, and resource allocation. It provides a snapshot of the state's readiness to
respond to and recover from disasters and emergencies, serving as a critical tool for
identifying strengths, weaknesses, and areas for improvement. Each state is tasked with
submitting its SPR to FEMA on a regular basis, typically annually or as required by
federal regulations. The SPR is a dynamic document that evolves over time, reflecting
changes in the state's preparedness efforts, capabilities, and priorities. It serves as a basis
for dialogue and collaboration between state and federal agencies, facilitating the
alignment of resources and priorities to enhance overall preparedness and resilience.
By requiring states to maintain a current SPR, PKEMRA aims to promote
transparency, accountability, and effectiveness in the administration of federal
preparedness assistance. It ensures that federal funds are allocated to states with
demonstrated readiness and capacity to effectively manage emergencies and disasters,
thereby enhancing the nation's collective ability to mitigate, prepare for, respond to, and
recover from a wide range of threats and hazards. In summary, the requirement for states
to maintain a current SPR under PKEMRA underscores the importance of preparedness
planning and assessment in building resilient communities and enhancing national
security. It reflects a commitment to proactive risk management and continuous
improvement in emergency management practices, positioning the nation to better
withstand and recover from the myriad challenges posed by disasters and emergencies.
The THIRA requirement, as it applies to the FEMA preparedness grant recipients,
must be completed by December 31 of each year as a condition of their federal grant
funding. Jurisdictions must allow considerable time for the process to be completed by a
capable team of knowledgeable professionals Emergency management agencies
participate in THIRA because they are mandated to do so when we receive federal
preparedness grants. The process best serves both individual states and the nation as a
whole when it trickles down to the local level and is initiated with good guidance and
support. States will collate the results of local governments when they generate their own
products.
Indeed, the efficacy of the THIRA process at the local level serves as a linchpin
for the success of preparedness efforts at the state and national levels. As the foundational
building block of the broader emergency management framework, the quality and
thoroughness of THIRA implementation at the grassroots level have ripple effects that
reverberate upward, shaping the overall resilience and readiness of the entire nation. At
the local level, where the rubber meets the road, emergency managers are uniquely
positioned to gain intimate knowledge of their community's specific vulnerabilities,
strengths, and needs. By conducting thorough and meticulous THIRA assessments, local
stakeholders can identify and prioritize the most pressing risks facing their jurisdiction,
laying a solid foundation for targeted preparedness planning and resource allocation.
Moreover, the local level serves as the crucible in which preparedness measures
are put to the test, providing valuable insights into the efficacy of response and recovery
strategies in real-world scenarios. By fostering a culture of continuous improvement and
learning, local THIRA implementation enables communities to refine and adapt their
preparedness efforts over time, enhancing their resilience to evolving threats. At the state
and national levels, the aggregation and synthesis of THIRA results from local
jurisdictions play a crucial role in informing broader preparedness strategies and resource
allocation decisions. State emergency management agencies, tasked with coordinating
and supporting local jurisdictions, rely on the insights gleaned from local THIRA
assessments to identify statewide trends, gaps, and priorities.
Similarly, FEMA regional offices play a pivotal role in collating THIRA results
from the states they serve, synthesizing this information to generate comprehensive
regional risk profiles and preparedness plans. These regional products provide valuable
context and insights into cross-jurisdictional risks and vulnerabilities, informing strategic
decision-making and resource allocation at the federal level. Ultimately, the strength of
the THIRA process lies in its ability to foster collaboration, coordination, and
information-sharing across all levels of government and the private sector. By harnessing
the collective wisdom and expertise of stakeholders at the local, state, and national levels,
the THIRA process empowers communities to build resilience and adaptability in the
face of a dynamic and ever-changing threat landscape.
B. THIRA by The Numbers
In Step 1 of the THIRA process, emergency managers need to develop a list of
community-specific threats and hazards. These include natural hazards, technological
hazards (accidents or systems failures), and human-caused incidents (such as terrorism).
Emergency managers should consult a number of different sources when attempting to
identify community specific hazards and threats. These sources include other documents
or assessments, historical data, intelligence from fusion centers, and whole community
partners. They should include only those threats and hazards that are of specific concern
to them. The two factors that must be considered here are likelihood of the incident and
significance of threat/hazard effects.
In navigating the labyrinth of hazards and threats that may besiege a community,
the role of an emergency manager is akin to that of a vigilant guardian, tasked with
discerning which potential dangers are not only feasible but also wield the potential to
inflict significant harm upon their jurisdiction. This delicate balancing act requires a
nuanced approach, one that hinges upon a meticulous examination of plausibility and
impact. At the heart of this endeavor lies the imperative to sift through a myriad of
conceivable risks, filtering out those that may loom large in the realm of imagination but
hold little weight in the realm of reality. While it may be tempting to entertain every
conceivable scenario, the pragmatic reality demands a more discerning eye, one that is
trained to discern between the plausible and the improbable.
Plausibility serves as the litmus test, the threshold that separates the probable
from the improbable. In the context of hazard and threat identification, plausibility hinges
upon a complex interplay of factors, including historical precedent, scientific evidence,
expert opinion, and situational context. It requires a judicious weighing of the available
evidence, a careful examination of past events, and a sober assessment of present
circumstances. Simultaneously, the lens of impact comes into focus, illuminating the
potential consequences of each plausible hazard or threat. Here, the yardstick of
significance serves as the guide, measuring the magnitude of potential harm in terms of
human life, property damage, economic disruption, and societal upheaval. A hazard or
threat may be plausible, yet its impact may be minimal, rendering it of lesser concern in
the grand scheme of preparedness planning.
Thus, to include specific hazards and threats in the THIRA process, the
emergency manager must tread a fine line, weighing the scales of plausibility and impact
with precision and care. It is not enough for a hazard or threat to merely exist in the realm
of possibility; it must also possess the potential to wreak havoc and wreak it to a degree
that warrants serious consideration. In essence, the inclusion of hazards and threats in the
THIRA process is not a matter of mere conjecture or speculation; it is a matter of sober
assessment and informed judgment. It requires the ability to discern between the
conceivable and the improbable, the significant and the trivial, the plausible and the
fanciful. By carefully considering what hazards and threats are both plausible and
significant, emergency managers can develop a THIRA that provides a realistic and
actionable assessment of the risks facing their community.
Indeed, in the process of conducting a Threat and Hazard Identification and Risk
Assessment (THIRA), it is imperative to focus on hazards and threats that are both
plausible and pose a significant level of risk to the community. Hazards and threats that
are not plausible, possible, or serious should be excluded from the THIRA, as they could
potentially divert resources and attention away from addressing more pressing risks. The
exclusion of implausible hazards and threats ensures that the THIRA process remains
efficient and effective, allowing communities to allocate their limited resources towards
addressing the most pertinent risks. By focusing on plausible and serious hazards and
threats, communities can develop more targeted and impactful preparedness strategies,
thereby enhancing their overall resilience and ability to mitigate the impact of disasters.
Moreover, excluding non-plausible hazards and threats helps maintain the
credibility and legitimacy of the THIRA process. By ensuring that the assessment is
grounded in evidence-based risk analysis and informed decision-making, stakeholders
can have confidence in the results and outcomes of the assessment. This, in turn, fosters
greater collaboration and buy-in from key stakeholders, facilitating the implementation of
preparedness measures and enhancing overall community resilience. In summary, the
exclusion of hazards and threats that are not plausible, possible, or serious is a
fundamental principle of the THIRA process. By focusing on the most pertinent risks,
communities can develop more effective preparedness strategies and enhance their
resilience to disasters and emergencies.
Step 1 of the process yields a comprehensive compilation of plausible and
significant threats and hazards faced by a community. This initial phase serves as the
bedrock upon which subsequent preparedness and mitigation efforts are built, providing a
clear understanding of the diverse array of risks confronting the community. The output
of Step 1 is more than just a mere list; it is a meticulously curated inventory that
encapsulates the multifaceted nature of potential threats and hazards. These threats and
hazards may stem from various sources, including natural phenomena such as hurricanes,
earthquakes, floods, wildfires, and severe storms. Additionally, they encompass the realm
of human-induced hazards, such as industrial accidents, chemical spills, transportation
incidents, and acts of terrorism. Furthermore, in today's interconnected world, the list
may also include emerging threats like cyberattacks and pandemics, which pose unique
challenges to community resilience. Each threat and hazard identified in Step 1 is
carefully evaluated for its probability of occurrence, potential magnitude of impact, and
geographical relevance to the community. Through rigorous analysis of historical data,
scientific research, and expert assessments, the list is refined to include only those threats
and hazards deemed both plausible and significant.
Moreover, Step 1 goes beyond mere enumeration, providing context and insights
into the specific characteristics and dynamics of each threat and hazard. This includes
considerations such as the seasonality of natural disasters, the vulnerability of critical
infrastructure, the presence of high-risk facilities or populations, and the potential
cascading effects of interconnected hazards. Ultimately, the output of Step 1 serves as a
critical foundation for the subsequent steps in the preparedness process. It empowers
communities to prioritize their efforts, allocate resources effectively, and tailor their
preparedness strategies to address the most pressing risks and vulnerabilities. Armed with
this comprehensive understanding of their threat landscape, communities are better
equipped to develop robust emergency plans, enhance resilience, and protect the safety
and well-being of their residents.
In Step 2 of the THIRA, emergency managers need to add context descriptions for
each threat and hazard identified in Step 1. Context descriptions outline conditions,
including time and location, under which a threat or hazard might occur. We can use
expert judgment and analysis to provide us with better descriptions of the conditions we
might expect. Threats and hazards are likely to have different impacts depending on the
time, place, and conditions in which they occur. Emergency managers should develop
more than one context description for each hazard or threat listed. Community planners
should take into account past experiences, but they should realize that the past may not be
a good predictor of the future.
The third step in the THIRA process is probably the most difficult for any
emergency manager. In this step, communities need to establish capability targets for
each core capability. Where do these core capabilities come from in the first place? They
were described in the NPG, which comes from DHS and FEMA The NPG was mandated
by Presidential Policy Directive (PPD) 8: “National Preparedness,” which was released in
April 2011, and it was originally published the following October. In the NPG,
capabilities were detailed within five distinct Mission Areas (Prevention, Protection,
Mitigation, Response and Recovery). The NPG defines what it means for a whole
community to be prepared for all types of disasters and emergencies.
The array of risks confronting society encompasses a wide spectrum of events,
spanning from the wrath of natural disasters to the intricacies of disease pandemics, the
perils of chemical spills, and the complexities of man-made hazards. Among these risks
are also the looming threats of terrorist attacks and the ever-evolving landscape of
cyberattacks. Each of these potential calamities poses significant challenges to the safety,
security, and resilience of communities, necessitating a multifaceted and vigilant
approach to preparedness and response. Embedded within the fabric of preparedness
doctrine lies a pivotal document that not only articulates the overarching goal of
enhancing national preparedness and resilience but also meticulously outlines 31
activities, dubbed core capabilities, which constitute the bedrock of readiness efforts.
These core capabilities, meticulously crafted to address the most pressing risks
confronting the nation, serve as beacons guiding preparedness endeavors across diverse
sectors and disciplines.
Comprising strategies and interventions aimed at thwarting, deterring, and
mitigating the occurrence of terrorist activities, criminal acts, and other threats to public
safety and security. Encompassing measures devised to shield critical infrastructure, key
assets, and essential services from physical and cyber threats. These measures encompass
the development and implementation of robust security protocols and risk mitigation
strategies. Focused on endeavors to diminish the likelihood and severity of disasters and
emergencies through a gamut of activities, including risk reduction, hazard mitigation,
strategic land-use planning, and infrastructure enhancements. Encompassing the panoply
of actions undertaken to preserve lives, safeguard property, and ensure public safety
amidst emergencies and disasters. Response efforts span from emergency operations and
search and rescue missions to the provision of medical aid and humanitarian assistance.
Envisioning initiatives aimed at facilitating the restoration of essential services, the
reconstruction of infrastructure, and the revitalization of communities ravaged by
disasters. Recovery endeavors entail a comprehensive suite of actions geared toward
fostering resilience and fostering community renewal in the wake of adversity.
Aligned with each core capability are specific objectives, performance metrics,
and implementation strategies, collectively furnishing a comprehensive blueprint for
bolstering preparedness and resilience at all levels of governance. By grounding
preparedness efforts in these core capabilities and capability targets, stakeholders can
strategically allocate resources, harmonize collaborative endeavors, and fortify
institutional capacities to effectively confront and mitigate the myriad risks confronting
the nation.
To continue with the lengthy process in Step 3, capability targets must be specific
and measureable. To do this, a community must consider the impacts and the desirable
outcome for each threat and hazard. In keeping with what was covered in the last chapter,
impacts describe how a threat or hazard might affect us. Now, extend this effect to each
core capability. Since impacts are linked to the size and complexity of the hazard and
threat, one should realistically estimate the magnitude of that threat/hazard to gauge the
effect. The larger and more complex the hazard or threat, the more dramatic the impact
will be on that community. In addition, the effects on core capabilities will be greater.
C. Desired Outcomes
Desired outcomes describe the time frame or level of effort needed to successfully
deliver core capabilities. Capabilities are useful only if communities can deliver them in a
timely and effective manner. For example, success in the Response and Recovery mission
areas often requires communities to deliver capabilities within a certain time frame (e.g.,
complete search and rescue operations within 72 h). When considering desired outcomes,
communities should not be constrained by their current ability to meet time frames or
other conditions of success. In this step of the THIRA process, emergency managers will
apply the results of Step 3. So, in summary, Steps 13 listed the threats and hazards,
provided a context description for each, stated the capability targets, and then examined
the impacts of each hazard and threat to see what resources would be needed to counter
the incident. Applying the results is also viewed as gap analysis, where we will look at
existing resources, compare them to what is needed, and try to determine what the
shortfalls are and how to counter them.
Capability estimation begins when THIRA team members identify the major
actions needed to achieve their capability targets. Mission-critical activities can be
gleaned from current community-level plans, as well as from the National Planning
Frameworks. Team members should consider the quantity and types of resources needed
to complete each missioncritical activity in support of the capability targets. THIRA team
members should avoid developing very detailed, tacticallevel task lists. Rather, they
should strive to identify resources at a management level of detail. Step 4 of the THIRA
process enables emergency managers to estimate how many resources—including
FEMA’s Tier I National Incident Management System (NIMS) typed resources—are
needed to achieve capability targets. In this step, communities develop a list of resource
requirements to meet the capability targets, while also considering preparedness activities
that may reduce future resource requirements.
THIRA, or the Threat and Hazard Identification and Risk Assessment, is a
systematic process mandated by the U.S. Department of Homeland Security (DHS) to
evaluate potential threats, hazards, and risks faced by communities. It serves as a
foundational element of emergency management, guiding stakeholders in identifying
vulnerabilities, prioritizing preparedness efforts, and enhancing overall resilience. This
process seamlessly integrates into a broader framework designed to help government
organizations comply with and achieve the objectives outlined in the National
Preparedness Goal (NPG), also established by DHS. The NPG outlines essential
capabilities and objectives necessary for enhancing preparedness and resilience across
various sectors, including government agencies, private entities, and non-profit
organizations.
THIRA begins with a comprehensive assessment of potential threats and hazards.
This involves analyzing historical data, intelligence reports, and expert assessments to
identify a wide range of risks, including natural disasters, terrorist activities, pandemics,
cyber threats, and more. Following the identification of threats, THIRA assesses the
existing capabilities and resources available to respond to and recover from emergencies.
This includes reviewing plans, policies, procedures, personnel, equipment, and training
programs to determine strengths, weaknesses, and areas requiring improvement. Based
on the assessment findings, organizations can prioritize their preparedness efforts.
THIRA assists in directing resources towards strengthening critical capabilities, such as
emergency response, public health readiness, infrastructure protection, and cybersecurity,
addressing the most significant risks and vulnerabilities. THIRA seamlessly integrates
into the National Preparedness System (NPS), which encompasses guidelines,
frameworks, and programs aimed at enhancing national preparedness and resilience. This
ensures that preparedness efforts are coordinated and aligned with those of other
stakeholders at the local, state, and federal levels.
Preparedness serves as the foundational framework upon which effective disaster
management is built, acting as a proactive strategy to mitigate the impact of unforeseen
crises and streamline response and recovery efforts. It encompasses a spectrum of
deliberate actions taken prior to disasters, aimed at fortifying communities, infrastructure,
and systems against potential hazards. Furthermore, for many, preparedness extends
beyond mere readiness for immediate response, encompassing the proactive identification
and implementation of measures aimed at reducing the likelihood and severity of future
disasters.
At its core, preparedness involves meticulous planning, comprehensive training,
and strategic resource allocation to ensure that communities are well-equipped to
navigate the complexities of disaster scenarios. This includes the development of
emergency plans tailored to the specific needs and vulnerabilities of the community,
delineating clear roles and responsibilities for stakeholders, and establishing robust
communication channels to facilitate coordination during crises. Conducting regular
training exercises and simulations is another vital aspect of preparedness, allowing
emergency responders and community members alike to familiarize themselves with
protocols, identify areas for improvement, and enhance their capacity to effectively
manage emergencies. These exercises serve as invaluable learning opportunities,
enabling participants to refine their skills, strengthen their teamwork, and bolster their
resilience in the face of adversity.
Investments in infrastructure resilience are also integral to preparedness efforts,
encompassing a range of initiatives aimed at reinforcing critical lifelines and
safeguarding key assets against the impacts of disasters. This may involve retrofitting
buildings to withstand seismic activity, constructing flood barriers to mitigate the risk of
inundation, or upgrading utility systems to enhance their reliability and resilience in the
face of extreme weather events. Moreover, preparedness encompasses the establishment
of early warning systems and public alert mechanisms to provide timely and accurate
information to residents, enabling them to take proactive measures to protect themselves
and their families. These systems play a crucial role in facilitating evacuation procedures,
disseminating critical safety instructions, and minimizing the loss of life and property in
the event of a disaster.
In addition to readiness for immediate response, preparedness also encompasses a
proactive approach to risk reduction through the identification and implementation of
mitigation strategies aimed at addressing underlying vulnerabilities and reducing the
likelihood of future disasters. This may involve land-use planning to mitigate the risk of
flooding or wildfires, implementing building codes and standards to enhance structural
resilience, or investing in ecosystem-based approaches to natural hazard mitigation. By
embracing a comprehensive approach to preparedness that encompasses planning,
training, infrastructure investments, early warning systems, and mitigation strategies,
communities can enhance their resilience and ability to withstand and recover from
disasters. Preparedness serves as a cornerstone of effective disaster management,
empowering communities to anticipate, mitigate, and respond to the myriad challenges
posed by natural and human-induced hazards.
Indeed, THIRA (Threat and Hazard Identification and Risk Assessment) plays a
pivotal role as a preparedness tool, guiding communities in identifying threats and
hazards and subsequently addressing their capabilities to effectively prepare for, protect
against, respond to, recover from, and mitigate dangerous events. Through a structured
and systematic process, THIRA facilitates a comprehensive understanding of the risks
facing communities, enabling the development of targeted strategies to enhance
resilience. The initial step in the THIRA process involves the identification and
assessment of a diverse array of threats and hazards that could potentially impact a
community. These may encompass natural disasters such as hurricanes, earthquakes,
floods, and wildfires, as well as human-caused events like terrorist attacks, industrial
accidents, and cyber-attacks. By conducting a thorough analysis of potential risks,
THIRA ensures that no threat is overlooked, laying a robust foundation for preparedness
planning.
Following the identification of threats and hazards, THIRA evaluates the
community's capabilities across various functional areas, including preparedness,
protection, response, recovery, and mitigation. This assessment scrutinizes the resources,
plans, policies, procedures, and partnerships in place to address each hazard. By
examining capabilities in these key areas, THIRA assists in identifying strengths,
weaknesses, and gaps in the community's readiness to effectively manage emergencies
and disasters. THIRA then guides communities in enhancing their functional
preparedness by addressing identified gaps and weaknesses in their capabilities. This may
entail developing or updating emergency plans and procedures, conducting training and
exercises to ensure readiness, enhancing coordination and communication among
stakeholders, and securing necessary resources and equipment. By focusing on functional
preparedness, THIRA ensures that communities are well-equipped to respond effectively
to a wide range of threats and hazards.
What distinguishes THIRA is its holistic and comprehensive approach to
emergency management. Rather than focusing solely on response and recovery, THIRA
emphasizes a cyclical preparedness cycle encompassing all phases of emergency
management: preparedness, protection, response, recovery, and mitigation. By addressing
capabilities across each phase, THIRA enables communities to build resilience and
adaptability in response to a changing threat landscape. Moreover, THIRA is not a one-
time endeavor but an iterative process that evolves over time. As new threats emerge,
community demographics change, and capabilities are enhanced, THIRA allows
communities to continuously assess and refine their preparedness efforts. By regularly
updating and revisiting the THIRA process, communities can stay abreast of emerging
threats and ensure that their resilience strategies remain effective and relevant.
THIRA is a process that allows organizations at all levels of government to
identify, assess, and prioritize their natural and manmade risks. These assessments are
meant to facilitate the identification of capability and resource gaps and allow
organizations to track their year-to-year progress to address those gaps. The purpose of
the THIRA process is to build unity of effort and a common strategic understanding
among all levels of government. THIRAs should employ existing hazard mitigation
processes, but in a reasonably standard manner so that results may be incorporated into
state-, regional-, and national-level assessments.
Using these assessments, emergency managers can develop planning assumptions
and, working with their regional partners, identify and implement priority actions to
address the identified shortfalls. The THIRA process provides a detailed and systematic
understanding of the risks and hazards that a community may face, along with an analysis
of the community's vulnerabilities and capabilities. This information is essential for
forming a solid foundation for effective emergency planning and preparedness. First, the
assessments generated by THIRA enable emergency managers to develop realistic and
informed planning assumptions. Planning assumptions are the scenarios and conditions
that planners consider when developing emergency response and mitigation strategies.
These assumptions might include the likelihood and potential severity of various
hazards, the resources available for response, and the timeframes within which specific
actions need to be taken. By considering these factors, emergency managers can create
comprehensive and effective plans that address the unique risks and needs of their
communities. One of the critical planning assumptions is the assessment of the likelihood
and potential severity of different hazards. This involves analyzing historical data,
climate trends, and current threat intelligence to predict the probability of various events
occurring and their potential impact. The likelihood of hurricanes, earthquakes, floods,
and wildfires can be estimated based on geographic and climatic data. For example,
coastal regions might prepare for hurricanes and storm surges, while areas near fault lines
focus on earthquake preparedness.
Assessing the threat of terrorist attacks, industrial accidents, and cyber-attacks
involves a multifaceted approach that encompasses understanding the intent and
capability of potential adversaries, as well as vulnerabilities in critical infrastructure. This

managers can ensure they are well-equipped to handle emergencies.
The importance of timeframes for specific actions cannot be overstated. Early
warning systems play a pivotal role in providing timely alerts about impending disasters.
Reliable weather alerts, seismic monitors, and public notification systems are essential
for giving residents the information they need to take protective measures. For instance, a
robust early warning system for hurricanes can give communities several days to prepare
and evacuate, significantly reducing the risk of injury and loss of life. Evacuation plans
are crafted with precision, taking into account the time needed to move people to safety.
This includes managing traffic flow, ensuring public transportation is available, and
addressing the needs of vulnerable populations, such as the elderly and disabled. Clear
and well-practiced evacuation routes and procedures can make a significant difference in
the efficiency and effectiveness of an evacuation.
Immediate response efforts are planned to ensure rapid mobilization of resources
during the critical first 72 hours after a disaster. This phase often involves search and
rescue operations, providing medical care, and delivering initial relief supplies.
Emergency managers coordinate with local, state, and federal agencies to streamline
these efforts, ensuring that help arrives where it is needed most without delay. Long-term
recovery plans are also essential, as rebuilding and restoring services can take months or
even years. These plans address the restoration of infrastructure, the resumption of
normal services, and the provision of ongoing support to affected individuals and

society capable of withstanding and recovering from the challenges posed by natural and
human-caused disasters.
With these planning assumptions in place, emergency managers can develop
targeted mitigation strategies that address specific vulnerabilities and enhance overall
resilience. In summary, the assumptions regarding the likelihood and potential severity of
hazards, the resources available for response, and the timeframes for specific actions are
foundational elements of emergency planning. By carefully evaluating these factors,
emergency managers can create robust, effective plans that enhance community
preparedness and resilience, ultimately reducing the impact of disasters and improving
the speed and effectiveness of response efforts.
For example, if THIRA identifies a high risk of flooding in a particular area,
emergency managers can assume that there will be significant water damage, disruption
to transportation networks, and potential displacement of residents. These assumptions
help to create specific, actionable plans that address the expected conditions during an
emergency. Once planning assumptions are established, emergency managers can work
closely with their regional partners to identify and implement priority actions. Regional
partners might include neighboring jurisdictions, state and federal agencies, non-profit
organizations, and private sector entities. Collaboration with these partners is crucial, as it
ensures a coordinated and comprehensive approach to emergency management. Priority
actions are the steps that need to be taken to address the gaps and shortfalls identified
during the THIRA process. These actions are aimed at enhancing the community’s
preparedness and resilience by focusing on the most critical areas of need. For instance, if
the THIRA assessment reveals a shortage of emergency shelters in the event of a large-
scale evacuation, a priority action might be to identify additional shelter locations and
ensure they are equipped with necessary supplies and personnel.
Implementing priority actions often involves a multi-faceted approach, including
policy changes, resource allocation, training, and public education. Emergency managers
might advocate for updated building codes to improve the structural integrity of buildings
in earthquake-prone areas or implement zoning regulations that restrict development in
floodplains. Based on the THIRA assessments, resources can be allocated more
effectively. This might involve investing in new equipment, such as flood barriers or
wildfire suppression tools, or enhancing existing infrastructure, like reinforcing bridges
and dams. Regular training and emergency drills are essential to ensure that emergency
responders and the community are prepared for various scenarios.
Indeed, the Threat and Hazard Identification and Risk Assessment (THIRA)
process plays a pivotal role in identifying specific training needs tailored to the unique
hazards and threats facing a community. By conducting a thorough assessment of
potential risks and their associated impacts, emergency managers can pinpoint areas
where specialized training is essential to enhance preparedness and response capabilities.
THIRA assessments provide valuable insights into the types of hazards and threats that
communities may face, ranging from natural disasters like floods and hurricanes to
human-induced incidents such as terrorist attacks or industrial accidents. Through this

addressing identified shortfalls and enhancing preparedness, communities can
significantly improve their ability to withstand and recover from disasters, ultimately
leading to a safer and more resilient society.
Understanding the risks faced by communities and the nation as a whole is
essential to national preparedness. The THIRA process provides a common and
consistent approach for communities to support the first two components of the National
Preparedness System: (i) identifying and assessing risk and (2) estimating capability
requirements. It expands on existing local, state, tribal, and territorial hazard
identification and risk assessment processes. THIRA contributes to a much broader
approach that helps the United States achieve its NPG of “a secure and resilient nation
with the capabilities required across the whole community to prevent, protect against,
mitigate, respond to, and recover from the threats and hazards that pose the greatest risk.”
THIRA is not a substitute for comprehensive hazard mitigation planning. On the other
hand, the products of THIRA may be incredibly useful in hazard mitigation planning.
THIRA is a comprehensive risk assessment process used by emergency management
agencies to understand and address the full spectrum of potential threats and hazards that
a community may face. By identifying and assessing these risks, communities can better

hurricane preparedness, while an inland area prone to wildfires might prioritize
vegetation management and emergency evacuation routes.
Another key output of THIRA is the estimation of the potential impacts of
identified hazards. This involves assessing the likely consequences of different scenarios,
including the number of people affected, the extent of property damage, and the potential
disruption to critical infrastructure. Understanding these impacts helps communities
prioritize their mitigation efforts and allocate resources effectively. For instance, if a
particular hazard is likely to cause significant damage to a vital bridge, the community
can invest in reinforcing the structure or developing alternative transportation routes.
THIRA also facilitates the development of capability targets, which are
benchmarks for the level of preparedness a community should aim to achieve. These
targets are based on the identified risks and the desired outcomes for each hazard
scenario. By setting clear, measurable goals, communities can track their progress over
time and ensure that their mitigation strategies are effective. For example, a community
might set a capability target to ensure that emergency shelters can accommodate a certain
percentage of the population during a major disaster. Furthermore, the THIRA process
encourages collaboration and communication among various stakeholders, including
government agencies, non-profit organizations, private sector partners, and the public.
This collaborative approach ensures that all relevant parties are involved in the planning
process and that the resulting mitigation strategies are comprehensive and well-
coordinated. Building resilient communities hinges on the cultivation of robust
