Where are Tsunamis Most Common
They are most Common In the Pacific and Indian Ocean. They are most common there because that is where the bigger earthquakes happen. They happen there because of the tectonic plates, when they move it makes a very big jolt in the water to make a wave. A lot of the time it is the Pacific plate moving agents the Eurasia Plate and the Australia Plate that makes the bigger waves. There can also be a lot of movement from the Africa Plate and the Eurasia Plate.

Facts about Tsunamis.
About 80% of tsunamis happen within the Pacific Ocean’s “Ring of Fire.”
The states in the U.S. at greatest risk for tsunamis are Hawaii, Alaska, Washington, Oregon, and California.
In 2004, the Indian Ocean tsunami was caused by an earthquake with the energy of 23,000 atomic bombs. After the earthquake, killer waves radiating from the epicenter slammed into the coastline of 11 countries. The final death toll was 283,000.
Tsunami means “harbor wave” in Japanese (tsu = harbor + nami = wave), reflecting Japan’s tsunami-prone history.
Hawaii is always at great risk for a tsunami – they get about 1 per year and a severe one every 7 years. The biggest tsunami that occurred Hawaii happened in 1946, the coast of Hilo Island was hit with 30 ft waves at 500 mph (800kmh)
A tsunami is a series of ocean waves caused by an underwater earthquake, landslide, or volcanic eruption. More rarely, a tsunami can be generated by a giant meteor impact with the ocean. These waves can reach heights of over 100 ft.
The first wave of a tsunami is usually not the strongest, successive waves get bigger and stronger.
