Tsunamis are formed when there is a sudden displacement of a large volume of water, usually due to underwater earthquakes, volcanic eruptions, landslides, or meteorite impacts. The displacement creates a series of powerful waves that travel across the ocean at high speeds.
Tsunamis are dangerous because of their sheer force and speed. As they approach shallow waters near the coast, the waves slow down but increase in height, sometimes reaching several meters or even tens of meters high. When they hit the coastline, they can cause massive destruction by flooding low-lying areas, destroying buildings, and sweeping away everything in their path. The immense force of the waves can lead to loss of life, injuries, and severe damage to infrastructure. Additionally, tsunamis can also trigger secondary hazards such as fires, contamination of water sources, and long-term environmental impacts.
