This is how the most common tsunamis is caused.

Tsunamis



Tsunamis are powerful forces of nature mostly caused by earthquakes or land slides into large bodies of water.
Tsunamis can also cause more deaths than earthquakes because people don't prepare for a tsunami after a big earthquake. Tsunamis are huge waves generally in a series of two or more waves. It is possible for a tsunami to reach 100+ feet. Tsunamis can reach speeds of 500 mph under water. Almost 80% of all tsunamis occur in the famous ring of fire in the pacific plate. When a tsunami reaches the shore the speed of the wave may slow to about 30-40 mph. Tsunamis can be up to 60 miles wide and be as much as one hour apart. The typical tsunami only reaches heights of 10-20 feet. People often think that a tsunami is a single wave. But really a tsunami is a series of waves sometimes an 1hour to an hour and a half a part. Also it is possible for the tsunami waves to be just minutes apart. The first wave of a tsunamis is actually the least powerful of all the waves to come. The tallest tsunami on record occurred in Alaska on July 9th, 1958 in litany bay.

Tsunami's Common Names


The word tsunamis is derived from the two Japanese words Harbor And Wave. A few years ago the tsunamis were called Tidal Waves. Although in recent years that word has basically died out. Except in some movies and book titles. Another name for a tsunami was a seismic sea waves.

Tsunamis Facts


Tsunamis are caused by up to five different ways. Earthquakes are one of the major reasons. Another way is an volcanic eruption usually in the ocean. Also another possible way is to have meteorites hit the ocean floor and cause tsunamis but actually that doesn't happen that often. Next a Landslide would possibly cause a huge tsunami if there was a big enough volume of rocks that hit the floor of a bay. Finally an explosion that is big enough especially under water which could cause an shock wave through the water causing a tsunami basically.

General Info on tsunamis

A tsunami is capable of traveling the whole pacific ocean in less than 24 hours and not lose much energy of the waves in the process. Some tropical storms can cause storm surges that are large enough to be called meteotsunamis. There is a possible way to set off an explosion under water with an loud and sudden movement of water to cause an tsunami.Meteorites, Asteroids, Comets and other celestial objects can hit the ocean causing water to move in an violent motion. Possibly Causing am Mega Tsunami.
