Tsunamis are not like the waves you usually find rolling along an ocean. Those are created by wind offshore. Although some seas ...view middle of the document...
Research has shown that is proper warning had been in place that thousands of lives could’ve been saved.
The movement of the Indian-Australian plate, which moves around 6 cm north-east a year caused Sumatra to raise itself approximately 10 meters in a short space of time along the coast of around 1,200 meters. As this happened the Australian plate was sub-ducted beneath the Eurasian plate causing the quake.
Compared to the Pacific Ocean very few tsunamis occur in the Atlantic though Atlantic coastlines are far from safe and therefore need to be protected.
Any island with mass volcanic activity is at danger from tsunamis, such as the Canaries, they constitute a danger was shown 300 000 years ago when a part of the island El Hierro slid into the sea, triggering a mega-tsunami which carried rocks as high as a house for many hundreds of metres into the interior of the east coast of what is today the USA.
Due to the slight sub-duction of the African plate many tsunamis occur in the Mediterranean Sea. In fact one in ten tsunamis happen here. On average, one disastrous...
