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.
Subject: Undersea earthquakes and tsunamis How do undersea earthquakes cause tsunamis? By changing the shape of the seafloor. If an earthquake ruptures all the way to (or even just close to) the seafloor, then part of the seafloor will be raised or lowered. Imagine that the seafloor is raised. Seawater itself is almost incompressible, so by raising the seafloor the earthquake will also be raising the sea surface. The sea surface, however, likes to be horizontal. An extra lump of water at the surface will collapse under gravity to produce a series of waves, the tsunami.
