Tsunamis The term “tsunami” derives from the Japanese word harbor wave, despite the fact that a tsunami actually increases in height as it enters a habour (Yeats). A tsunami can be described as a seismic sea wave. These sorts of natural disasters are commonly caused by shallow earthquakes at subduction zones with a magnitude of at least 7 (Abbott), which causes such waves to shoot outwards towards coastlines up to 800 kilometres an hour (Yeats). However, it is not necessarily the speed of the wave that allows a tsunami to be powerful, rather the volume of water present (Yeats). In the process of a tsunami, there is a sudden outrushing of water from the coast as it approaches, then the great wave approaches on shore causing damage, and then recedes (Yeats).
Before the Tsunami Vegetation Indonesia is an archipelago, or grouping of islands, of more than 17,000 islands (Lamoureux) located between the Pacific and Indian Oceans near the equator. Many countries located around the equator, such as Indonesia, experience high biodiversity (species richness …show more content…
Before 2004, Indonesia had approximately 515 species: 126 birds, 63 mammals, and 21 reptiles, making Indonesian home to more animal species than any other country in the world (Lamoureux), and the most mammal rich country in all of Southeast Asia (Weightman). Still, there are thousands of endemic wildlife species living in Southeast Asia, and many have yet to be identified
