How a Tsunami Happens

Tsunami is a Japanese word: “tsu” meaning harbour and “name” meaning wave. Tsunami is waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.

Subduction of earthquakes are mainly effective in generating tsunamis, and occur where denser oceanic plates slip under continental plates.
