How does a tsunami happen?

A tsunami is a Japanese word that means “Harbour waves” as the harbours get destroyed whenever there is a tsunami. An earthquake, a volcanic eruption or underwater landslides can shift large amounts of ocean water. As a result, a huge tidal wave called tsunami is formed. This force caused by large and sudden displacement of the ocean creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
