How does a tsunamis start and how they develop?

Answer 1

Tsunamis start from the earth's plates rubbing together or an earthquake.

Answer 2

Tsunamis are typically triggered by underwater earthquakes, volcanic eruptions, or underwater landslides. When these events occur, they displace a large volume of water, creating a series of powerful waves that can travel across the ocean at high speeds. As the waves approach shallow coastal areas, they slow down and their energy is concentrated, resulting in a devastating surge of water onto land.
