Relationship between an earthquake and a Tsunami.

Tsunamis are usually triggered by earthquakes, volcanic eruptions and underwater explosions, landslides and other mass movements. Underwater earthquakes have caused almost all of the major tsunamis in history. Tsunamis happen when the seabed abruptly deforms and the water above it displaces vertically.

Which magnitude earthquakes may lead to Tsunamis.

An earthquake with a judge strength of more than 7.5 usually takes place to trigger a devastating tsunami. Most tsunamis are caused by flat, large earthquakes in subduction zones. More than 80% of the world’s tsunamis occur in the Pacific along the subduction zones of the Ring of Fire.

All earthquakes do not cause tsunamis. Usually, it requires four conditions for an earthquake to cause a tsunami: The earthquake must occur under the ocean or cause material to slide into the ocean. The earthquake must be strong, at least magnitude 6.
