Sumatra earthquake in 2004

Coordinates:  Latitude: 1° 00' 0.00" N    Longitude: 97° 30' 0.00" E An earthquake that took place in the Indian Ocean in 2004 took about 230,000 lives. In scientific circles, this earthquake is known as the Sumatra-Andaman, and the epicenter was located below the ocean surface at a length of 30 km. The catastrophe took place on December 26, 2004, about 160km west of Sumatra. At first, assessed at 9.0 degrees by Richter, it was later estimated that the magnitude of the earthquake was between 9.1 and 9.3 degrees and with that strength represented the third in the list of the strongest earthquakes ever recorded in the seismogram. When it comes to the length of time, it's the first, with a duration of between 8.3 and 10 minutes. The earthquake triggered a series of devastating tsunamis, which spilled along the coast of Indonesia and other parts of the Indian Ocean. The tsunami took over 230000 lives, mostly in coastal towns, where people were killed as well as tourists. He felt at the same time Bangladesh, India, Malaysia, Myanmar, Thailand, Singapore, and the Maldives.

It was originally estimated that the magnitude of the thunderstorm was 8.8 on the Richter scale. In February 2005, scientists revised the estimate to 9.0. The Tsunami Warning Center has accepted this figure. More recent studies in 2006 estimated that magnitude earthquake was 9.1-9.3. Dr. Hiro Kanamori of the California Institute of Technology believes that 9.2 is the appropriate value for this earthquake.

The main earthquake epicenter was about 160 km from the west coast of northern Sumatra, in the Indian Ocean, north of the island of Simeulue, at a depth of 30 km. A Tsunami earthquake was also felt in Bangladesh, India, Malaysia, Myanmar, Thailand, Singapore and the Maldives. The first one was the city of Lokg in Indonesia. Since 1900, the only earthquakes with larger proportions were the Earthquake in Chile in 1960, magnitude 9.5 and Earthquake in Alaska, 1960, magnitude 9.2 degrees on the Richter scale. The only major earthquake magnitude 9.0 was Earthquake at Kamchatka in 1952 and Earthquake in Tohoku in 2011. All four earthquakes created a tsunami in the Pacific Ocean. However, the number of deaths from them was considerably lower, primarily due to lower population density for longer and due to a good warning system in Japan.

The Indian Ocean 2004 tsunami arose as a result of the submarine Sumatra-Andaman earthquake on December 26, 2004. This tsunami killed some 275,000 people and ruined the coast, causing great damage from Indonesia to Somalia in Africa, making it one of the deadliest natural disasters in modern history.

The tsunami is a wave of waves, or in a free translation of the Gulf wave, signifies the appearance of large waves, great kinetic energy, devastating mechanical effects on the coast. A tsunami occurs due to the sudden displacement of large water volumes, such as, for example, parts of the ocean and the sea. This is most often caused by underwater earthquakes such as the Sumatra earthquake. This Tsunami, like everyone else, behaved very differently in deep and shallow waters. In deep seawater, tsunami waves make only a small coat of arms, they are barely noticeable and harmless. Mostly traveling at a very high speed of 500 to 1,000 km / h to slow down in shallow water just a few tens of kilometers per hour, but also created huge devastating waves. The scientists found in the Indonesian province of Aceh that the waves of the tsunami reached a height of 24 meters on the coast, and even up to 30 meters in some areas in the interior.

The radar noted that the maximum wave height in deep water was two hours after the earthquake was 60 cm. Unfortunately, these observations could not be used to alert, as satellites are not designed for this purpose, and data is used for analysis purposes. The tsunami's greatest wave power was in the east-west direction. For this reason, Bangladesh, located at the northern end of the Bengal Bay, had very few casualties despite the fact that the country is relatively near the epicenter. The distance itself is not a guarantee of security, so Somalia suffered more damage than Bangladesh despite being much further. The tsunami reached the coast of the states from fifteen to seven o'clock. The north of the island of Sumatra was hit very quickly, while Sri Lanka and the coasts of eastern India were hit by roughly 90 minutes to two hours later. Thailand was hit about two hours later, despite being closer to the epicenter, as the tsunami traveled slower in the Andaman Sea to the coast.
