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.
If we are going to attempt to assess the risk of a tsunami at some particular place on the planet, we must first understand how to make a tsunami. Earthquakes and volcanoes generate the great majority of tsunamis, and the theory of plate tectonics explains the cause of earthquakes and volcanoes. So, we'll start with the world's briefest review of plate tectonics. Plate tectonics is the Grand Unifying Theory of geosciences, but it's actually not that old.
