Tsunami is a Japanese word that means "harbor wave." It is a large wave caused by movements in Earth's outer layer, or crust, which move ocean water. For example, an earthquake or a volcano in the ocean could cause a tsunami.. Earth's crust is made up of pieces called tectonic plates.An earthquake happens when these plates push against each other so hard that one of them slips …

Earthquake Causes Tsunami. Energy accumulates in the overriding plate until it exceeds the frictional forces between the two stuck plates. When this happens, the overriding plate snaps back into an unrestrained position. This sudden motion is the cause of the tsunami - because it gives an enormous shove to the overlying water.

Nov 23, 2016 · A tsunami is a series of waves, not just a single wave. In the open ocean, tsunami waves can travel at speeds up to 800 km per hour or 500 mi. per hour, as fast as a jet plane. Tsunami waves may be small in the open ocean, but wave heights can increase substantially as they approach the shore (indicated by the colored dots).

What happens during a tsunami? Once the water is moved by an earthquake or other event, large waves like ripples spread out from the point where the water first moved. These waves can move quickly and for very long distances. Some tsunamis have been known to travel for thousands of miles across the ocean and travel at speeds of up to 500 miles ...
