Tsunamis are generated by abrupt massive movements (changes) in the sea floor. An eruption of a volcano in or adjacent to the sea may be accompanied by earthquakes, and an earthquake may move the sea floor sufficiently to generate a tsunami. A second possible way for a volcano to create a tsunami might be due to a landslide from the side of a volcano. Such a mass movement of material into the sea would also displace water, and could generate a tsunami. Additionally, sometimes volcanoes explode violently, and that mass movement of material could also create a tsunami.
These submarine volcanoes form high slope pillars over their craters as compared to their on surface counterparts, which is due to the rapid cooling effect of water and buoyancy. The process of tsunami generation in such cases can be understood through the concept of phreatomagmatic eruption. Such an eruption is an explosive interaction between water and magma, which produces fine grained tephra with the emission of magmatic gases and steam.
