Tsunamis: Causes, Effects and Differences
A tsunami us a large wave caused by a displacement of a large volume of water. A tsunami are the effect of a natural primary hazards meaning that they are a secondary hazard, mostly the result of tectonic activity. The Boxing Day tsunami was caused by the subduction of the indo-Australian plate boundary underneath the Eurasian plate (240km off the coast of Indonesia). In contrast, the Japan tsunami was caused by the Pacific Plate subducting under the North American plate. The Asian and the Japan tsunami’s both share the same magnitude, however the effects differ this can be explained by the differences in both contrasting: economies, perception of the natural hazard, and response/preparation.
The earthquake that caused the Boxing Day tsunami struck at 7:58am on December 26th 2004, but the earthquake a different earth quake that caused the Japan tsunami occurred at 2.46pm on the 11th March. The mage-thrust earthquake caused by the subduction of the Indo-Australian plate (oceanic) underneath the Eurasian plate (continental) involved a 20 meter uplift of the sea floor all the way along the fault line which was over 1000 km in length. The uplift of the sea floor displaced billions of cubic tons of water, thus setting in motion a tsunami wave which hit the coast of Indonesia within half an hour of the earthquake. The Earthquake released stored energy equivalent too more than 23’000 Hiroshima bombs. On the other hands 250 mile off the North East coast of Japan’s main island of Honsh, an earthquake is Sendi occurred on the fault between the destructive plate margin. This involved the Pacific plate subducting under the North American plate.
The contrasting economic effects of the Boxing Day and Japan tsunami differ widely due to the economic differences between the different areas. The Boxing Day tsunami cost $9.9 billion but the Japan tsunami cost $78 billion and was the most expensive natural disaster in the world history to date. The reason why the there is such as
