- Tsunamis are catastrophic waves generated by underwater movements, often due to earthquakes lifting the ocean floor.
- As tsunamis approach land, they grow in height and power, posing a severe threat to coastal areas.
- A significant vacuum effect occurs around 15 minutes before a tsunami hits, pulling water away from the shore.
- The majority of tsunamis occur within the geologically active region known as the Ring of Fire.

Tsunami is a catastrophic wave.
Formation and characteristics of tsunamis
Tsunamis are generated by underwater movements. A tsunami is produced when part of the ocean floor is lifted by an earthquake and the column of water above it starts moving. The nearer it gets to land, the higher and more powerful it becomes. About 15 minutes before a tsunami hits, there is a giant vacuum effect. Most tsunamis happen within the Ring of Fire. Tsunamis are very dangerous, if people don't pay attention. If you think that a tsunami is going to hit you must go in the highest place you find.
