Tsunamis
Tsunamis, also called seismic sea waves, are giant waves that sometimes crash through cities near the ocean. They are generally caused by earthquakes. I have done further research to dig deeper on subject about the power of a tsunami. To generate tsunamis, earthquakes must occur under or near the ocean, and has to be large and create movements in the sea floor. Anyone close to the ocean can experience a tsunami, but in the Pacific Ocean there is a much more frequent occurrence of large, destructive, tsunamis because of the many large earthquakes along the margins of the Pacific Ocean. The Pacific Ocean is surrounded by mountain chains, deep ocean trenches and island arcs, sometimes referred to as the "ring of fire." The great size of the Pacific Ocean and the large earthquakes associated with the "ring of fire" combine to produce deadly tsunamis. These are the major things that cause tsunamis and obviously it sounds like it does allot of damage. The largest recorded tsunami was a wave 1720 feet tall. On July 9, 1958, an earthquake along the Fairweather Fault in the Alaska Panhandle loosened about 40 million cubic yards of rock high above the northeastern shore of Lituya Bay. The force of the wave removed all trees and vegetation from elevations as high as 1720 feet above sea level. It was very devastating. This was the highest tsunami ever recorded, which happened in the Alaska Panhandle. Some of the things you should do if a tsunami had been warned to you. If you are in school and you hear there is a tsunami warning, you should follow the advice of teachers and other school staff. If you are at home and hear the tsunami warning, you should make sure your entire family is aware of the warning. Your family should evacuate your house if you live in a tsunami evacuation. Move in a calm and safe manner to the evacuation site or to any safe place outside your evacuation zone. Follow these things and you may come out alive. All of these things are important.
