A large seismic sea wave caused by a volcanic eruptions or earthquake?

A large seismic sea wave caused by volcanic eruptions or earthquakes is known as a tsunami. These waves occur when there is a sudden displacement of a significant volume of water, often due to tectonic activity. Tsunamis can travel across entire ocean basins at high speeds, and when they reach shallow coastal areas, they can grow to immense heights, causing devastating destruction. It's important to have early warning systems in place to mitigate the impact of such natural disasters.
