Tsunamis are large waves that are caused by underwater earthquakes. Tectonic plates rub together, as if a earthquake was forming but underwater. Once all of this forms the waves start moving and getting bigger and sooner or later, the tsunami could take out a city! Tsunamis can move hundreds of miles per hour in the ocean and smash into land with waves as high as 100 feet or more. From the area that the tsunami forms, waves can move outward in all directions. All tsunamis are dangerous, even though they may not hit all of the coastline.
80% of the tsunamis happen within the Pacific Ocean's "Ring Of Fire." Experts always recommend to go 50 feet above sea level during tsunamis.
The video above shows a tsunami, that happened in Thailand 2004. It is said to be the most devastating tsunami recorded in modern history. It sadly killed more than 250,000 people.
