What causes a tsunami?
A tsunami is caused primarily by underwater earthquakes, but can also be triggered by volcanic eruptions, landslides, or meteorite impacts. When these events displace a large amount of water, it creates waves that travel across the ocean at high speeds, growing in height as they approach shallower coastal areas.
