What is the cause of japan's tsunami?

In: Geography, Tsunamis [Edit categories]

Answer:

An earthquake under the sea very close to Japan. Earthquakes are caused by the readjustment of the techtonic plates, and this is because the tectonic plates were converging into each other and since continental plates are more dense than oceanic plates the oceanic plates subducted into the mantle causing an earthquake under the sea. The waves slowly rolled across the ocean causing the waves to get larger as they were moving away from the focus point.
