The highest tsunami ever recorded was in 1971 near Japan at 280 feet high.

What is a tsunami?Also known a tidal wave, a tsunami is a huge wave that can be hundreds of feet high and over a hundred miles long.

Tsunamis

A tsunami froms when there is an underwater earthquake. The waves from the quake move fast in deep water and when they hit shallow waer, they pile up on top of each other to form a collasal wave.

The deadliest tsunami recorded was in 2004 in the Indian Ocean and claimed 310,000 lives.

Not only do tsunamis take peoples lives when they strike but they also take the buildings away. This can lead the survivors to have to start their life over again. Their home would be destroyed and even the place they work at. This can damage not only them but the economy as a whole.

The desrtuction of a tsunami is measured on a scale of 1 to 12 with 1 being the weakest and 12 the strongest. This scale is know as the Tsunami Intensity Scale.

Coastlines are the most vulnerable to tsunamis with the most vulnerable being the coastlines of Honshu in Japan, Hawai, Alaska, Indonesia, Peru, Ecuador.

Thereis no real defense against a tsunami except moving to a location that is safer. If one does strike, one must know evacuation routes and mentally prepare for the desrtuction to come.
