Earthquakes are one of the most dangerous and life threatening natural disasters known to mankind. Earthquakes can happen at any time and anywhere without warning. There are many earthquakes that happen every day with only minor tremors that are not felt by humans. However, there are some earthquakes big and strong enough to cause damage at very high levels. Earthquakes have a very long history of destruction. The Earth’s crust is filled with slowly moving plates. These plates are in constant motion under the surface of the Earth. As the size of the plates increase, the movement speed of the plates increase. When these large plates break apart from their own boundaries, they move into the path of other plates. When these plates…show more content…
However, there is a subduction zone that is to the west of Indonesia, but large earthquakes and tsunamis do not happen very often in the Indian Ocean so there is no way to recognize there is a problem (Osborne). With the Indian Ocean not getting large earthquakes and tsunamis very often, the islands are not as prepared for these destructive events like Japan, for example, is for these natural disasters. The earthquake happened 160 km west of the northern part of Sumatra and at a depth of about 30 km, which is fairly shallow waters. This earthquake caused a displacement of the seabed that resulted in a cliff line which released an amount of energy that is equivalent to 23,000 Hiroshima-type of atomic bombs (Osbourne). This earthquake was unexpected to happen at the location that it did. According to previous research, the Indian Ocean was not vulnerable to such a strong earthquake (Osbourne). Although the earthquake did not cause the damage, the tsunami that it created was a deadly and destructive force that the people were not prepared for. Tsunamis are caused by underwater earthquakes that displaces a large amount of water. The December 26, 2004 earthquake caused a deadly tsunami that is one of the most destructive tsunamis to ever happen. The 9.1-9.3 earthquake lasted for ten minutes and caused a fault line that stretched 750 miles to move up 40 feet. This movement of the earth pushed boulders
