Answer:
Explanation:
A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. ... But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. The speed of tsunami waves depends on ocean depth rather than the distance from the source of the wave.
A powerful undersea earthquake that struck off the coast of Sumatra island, Indonesia, set off the 2004 Indian Ocean tsunami, also known as the Christmas or Boxing Day tsunami, on Sunday morning,
Tsunamis not only destroy human life, but have a devastating effect on insects, animals, plants, and natural resources. A tsunami changes the landscape. It uproots trees and plants and destroys animal habitats such as nesting sites for birds.
Answer:
Tsunami is a series of ocean waves typically caused by large undersea earthquakes or volcano eruptions at tectonic plate boundaries. These surges of water may reach 100 feet and cause widespread destruction when they crash ashore. They race across the sea at a speed up to 500 miles per hour and cross the entire Pacific Ocean in less than one day. Their long wavelength means that they lose very little energy along the way.
Tsunami of December 2004, caused by a 9.0 magnitude earthquake, is the most infamous tsunami of modern times with disastrous consequences in many areas [1]
(i) humanitarian toll: it affected more than 18 countries from Southeast Asia to Southern Africa, killing more than 250,000 people in a single day and leaving more than one million homeless,
(ii) economic toll: it left several million of dollars of economic loss affecting fishing and tourist industries,
(iii) environmental and medical threats including water pollution and flooding and endemic diseases.
The rationale for writing this paper is to report the tsunami events in the eleven nations bordering the Indian Ocean, as they received less publicity than their Southeast Asian countries counterpart although the 2004 tsunami had real humanitarian, economic, and environmental impact in these regions more than 1,000 miles away from the epicenter [2].
Furthermore, these regions are at risk from the devastating effects of future tsunami due to the presence of a tectonic interactive plate [3], absence of a tsunami warning system in the Indian Ocean, and lack of established communication network providing timely information to that region.
These eleven countries bordering the Indian Ocean are Mauritius, Madagascar, Reunion Island, and Seychelles, Comoros islands and by geographical extension include countries in southern borders of Africa such as Somalia, Tanzania, Mozambique, and South Africa.
These individual countries suffered humanitarian loss with more than 3,000 people killed and left more than 10,000 homeless about 1,000 miles away from epicenter. In terms of economic toll, several million dollars were reported accompanied by environmental threat due to flooding.
