Transcript of Tsunamis

Tsunamis Tsu means harbor
Nami means wave A tsunami (pronounced sue-nahm-ee) is a lot of huge waves that destroy most things in it’s path plus there is usually loss of life. Underwater earthquakes cause most tsunamis. 90% of tsunamis are in the Pacific Ocean. In order to cause a tsunami the earthquake has to be more than 6.75 on the Richter scale (a measurement for earthquakes). A tsunami is when a huge volume of water moves quickly. Two parts of an ocean floor may shift in opposite directions in an earthquake. Then the water moves quickly. The resulting wave is not very tall in deep water. You can’t see it very well out in the ocean. Then it spreads across the ocean in all directions at great speeds. It can go as fast as a jet (about 600 mph). A regular wave (caused by winds) travels about 45 mph. The run up is usually more dangerous than people think. It has a lot of force. Enchanted Learning

Or if you’re on the coast and you experience an earthquake, you should also run towards higher ground. Some beaches have warning sirens. The first wave isn’t usually the largest. comparison between tsunami and regular wave You cannot outrun a tsunami. And the force topples buildings with little effort. A person is no match for a tsunami. When it hits the shore it slows down which makes the force transfer to a much taller wave than it was in the ocean.
