How do tsumanis form?

Answer 1

Tsunami's can be formed by earthquakes, volcanic eruptions, and rarely, a landslide or meteorite.

When earthquakes start, most of the time, large areas on the ocean floor is suddenly elevated or subsided. All of the energy released from that pushes the water up and as more energy is released, more water comes up. And thus, it creates a tsunami.

Volcanic eruptions can also cause earthquakes.

Landslides are very rare. But when landslides do create a tsunami, it is referred to as a mega tsunami. And is a LOT more dangerous than a regular tsunami (not sure how much stronger). For a landslide to create a tsunami, you would need at least around 90 million tons of rock hitting the water simultaneously.

Answer 2

Tsunamis are typically generated by underwater earthquakes, volcanic eruptions, or landslides. When these events occur, they displace a large volume of water, causing a series of powerful waves to form and travel across the ocean at high speeds. When these waves approach shallow coastal areas, they can grow in height and cause devastating flooding.

Answer 3

80% of the worlds tsunamis occur in the Pacific Ocean.

Answer 4

earthquakes in the seabed floor
