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.
1 Pressure builds and magma explodes to the surface causing a volcanic eruption. 2  The lava from the eruption cools to form new crust. 3  After several eruptions, the rock builds up to form a volcano.4  The magma chamber is a collection of magma below the volcano.ey points. 1  Volcanic eruptions can happen at destructive and c onstructive boundaries. 2  Volcanoes form when magma rises through cracks or weaknesses in the Earth's crust. 3  Pressure builds and magma explodes to the surface causing a volcanic eruption. 4  The lava from the eruption cools to form new crust.
