The Sumatra-Andaman Earthquake Epicenter Coursework
The Sumatra-Andaman Earthquake Epicenter - Coursework Example There were 227,898 estimated casualties (confirmed death toll=184,167) caused by the tsunami. In Indonesia alone, there were 130,736 people confirmed dead. In Tanzania, on the other hand, there was only 10 confirmed death report caused by the tsunami incident. Yes, there was more than one tsunami that occurred in the 2004 Indian Ocean Earthquake. The first two successions of waves produced by the tsunami had 30 minutes gap. Afterward, the third wave occurred an hour and a half later. The third wave was the most powerful among the tsunami waves. During the earthquake, the seabed abruptly rises in the vertical direction by several meters. Eventually, massive volumes of water are displaced resulting in a tsunami that damaged or struck the affected areas. There are two visible signs before the tsunami strikes in some places. First, the earthquake itself is the most obvious warning sign for the tsunami to occur. And second, when the sea recedes from the coastline like what happened around the Indian Ocean, it is already a sign that what may follow next is a fatal tsunami. 26. Why was the damage and life loss greater in Sri Lanka than in Bangladesh? Assume that a) the countries are the same distance from the epicenter, and b) both countries have low-lying coastal land). FYI, the effects in Africa (Somalia, for example) were greater than in Bangladesh. The reason why Sri Lanka has greater damage or death toll in contrast to Bangladesh is that of the nature of the earthquake in relation to the rupture zone. In fact, the Sumatra-Andaman earthquake proceeded more slowly in the direction towards the northern rupture zone. In the process, it gradually decreases the energy produced by the water displacement.
