TSUNAMI

A tsunami is a series of waves that is created when a large volume of a body of water, such as an ocean, is rapidly displaced. The Japanese term is literally translated into "(great) harbor wave."

Earthquakes, volcanic eruptions and other underwater explosions (detonations of nuclear devices at sea), landslides, collides impacts, and other mass movements above or below water all have the potential to generate a tsunami. Due to the immense volumes of water and energy involved, the effects of tsunamis can be devastating.

The Greek historian Thucydides was the first to relate tsunami to submarine quakes, but understanding of the nature of tsunami remained slim until the 20th century and is the subject of ongoing research.

Many early geological, geographical, and oceanographic texts refer to tsunamis as "seismic sea waves."

Some meteorological storm conditions such as deep depressions causing cyclones, hurricanes, can generate a storm surge which can be several meters above normal tide levels. This is due to the low atmospheric pressure within the center of the depression. As these storm surges come ashore, they may resemble (though are not) tsunamis, inundating vast areas of land. Such a storm surge inundated Burma (Myanmar) in May 2008.

If there is a tsunami, go to the mountaints or hop on roofs and you should call someone, or call for help.
