Tsunamis happen most frequently in the Pacific Ocean because of the many large earthquakes associated with subduction zones along the margins of the Pacific Ocean basin, which is called the “Ring of Fire”. Subduction is the process of two converging tectonic plate movements. Copyright © 2011. The crust sticks in some places, storing up energy that is released in earthquakes.

Verbs for subduction include subduct, subducted, subducting and subducts. Why Do “Left” And “Right” Mean Liberal And Conservative? At the time that this happens the bottom plate is either forced into the Earth's mantle by the top plate or sinks due to gravity. What is a subduction zone? Where they collide and one plate is thrust beneath another (a subduction zone), the most powerful earthquakes, tsunamis, volcanic eruptions, and landslides occur. The massive scale of subduction zones means they can cause enormous earthquakes. If you would like to participate, you can choose to edit this article, or visit the project page for more information.

The Earth’s many tectonic plates can be thousands of miles across and underlie both continents and oceans. Subduction is the main cause of major tsunami events. (Subduction involves the descent of the edge of one lithospheric plate beneath that of another where two such plates collide.) Subduction zones are convergent boundaries where at least one of the tectonic plates is an oceanic crust.
