“Dettmer, J., Hawkins, R., Cummins, P. R., Hossen, J., Sambridge, M., Hino, R., & Inazu, D. (2016). Tsunami source uncertainty estimation: The 2011 Japan tsunami. Journal of Geophysical Research: Solid Earth, 121(6), 4483-4505.”

Summary

The article outlines research on the displacement of sea surface and its uncertainties after the occurrence of an earthquake founded on tsunami-genic waves. It establishes uncertainty levels through an approach known as Bayesian modeling. The parameters involved in this case are nonlinear, and the rupture velocity is assumed to be unknown. The rise time is taken to be thirty seconds.

Evaluation

The article is relevant in its content since it encompasses researches from which inferences are drawn. The approach used is also essential in that it displays the likelihood of occurrence. The method is known as Bayesian modeling.

Summary

The article talks about a tsunami that occurred in Sri Lanka a long time ago, more than 20 centuries back. It was caused by a mid-ocean earthquake that happened in the Indian Ocean, causing massive destruction and loss of lives. The article is divided into two sections. The first section is called "How to survive a tsunami." It outlines the features of tsunamis with giving examples. The second section called "Tsunami Behavior and Forecasting" describes the scientific aspects of a tsunami.

Evaluation

The article is relevant as far as its content is concerned. It aims at keeping the public informed as far as tsunamis are concerned. The prologue part of the article portrays much importance since it outlines some queries concerning tsunami, which people get to learn when they read the article.

Summary

The articles describe a flexible policy for tsunami cautioning based on seismic stations and locational geodetic stations. Retrospective scrutiny was carried out on four tsunamis that occurred in Japan and Chile, from which information regarding the sources of earthquakes and the tsunamis was acquired. It was clear that the occurrence of an earthquake is a predictor for a tsunami. The policy does not require that new seismic and geodetic instruments be deployed in different zones. Instead, it could enhance faster predictions through state monitoring and cautioning organizations.

Evaluation

The conclusion of the article regarding earthquake as a cause of tsunami occurrence is valid. The reason behind the validity is the fact that it was generated from comparisons carried out regarding the earthquake sources and the propagation of the tsunamis alongside the previously conducted surveys about tsunami backlog.
