What is Tsunami?
Imagine a giant wall of water growing out of the ocean, big enough to wipe out entire coastal towns and capable of killing hundreds of thousands of people caught in its path. This is the power created by a tsunami, which is a series of waves caused by an earthquake, underwater volcanic eruption, landslide or other abrupt disturbance. Tsunamis are capable of creating massive devastation when they hit land. In this lesson, you will learn how tsunamis are created and the effects they have on people and the environment.
The word tsunami comes from the Japanese language. The prefix 'tsu' means 'harbor' and the suffix 'nami' means 'wave.' Therefore, the word literally means 'harbor wave.
Causes for Tsunami and How Do They Form?
Tsunamis can be caused by any action that creates an abrupt disturbance underwater. This can include a volcanic eruption or landslide, and even a meteorite or nuclear explosion, although these last two examples are rare. The most common cause of a tsunami is an earthquake, which is a sudden shifting of the earth's crust, which releases energy. If an earthquake happens underwater, the seafloor lifts and then drops back down, causing the overlying water to be displaced and triggering waves of water.
