Tsunamis

What are Tsunamis?

Tsunamis are large ocean waves caused by underwater earthquakes, volcanic eruptions, or other underwater disturbances.

Formation of Tsunamis

When an underwater disturbance occurs, it displaces a large volume of water, resulting in the formation of a tsunami wave. The wave can travel across entire ocean basins at high speeds.

Characteristics of Tsunamis

• Tsunamis can travel at speeds of up to 500 miles per hour in deep ocean waters.
• They can have wavelengths of up to 200 kilometers and reach heights of over 30 meters as they approach the shore.
• As they approach the shallower coastal waters, the wave slows down and increases in height, causing catastrophic flooding and destruction.

Impact of Tsunamis

Tsunamis can cause widespread devastation, including loss of life, destruction of infrastructure, and long-term environmental damage.

Warning and Mitigation

Early warning systems, coastal barriers, and community preparedness are essential for mitigating the impact of tsunamis and saving lives.

Study Tips

1. Understand the causes and characteristics of tsunamis.
2. Learn about the historical tsunamis and their impact on coastal communities.
3. Be familiar with the measures taken to mitigate the impact of tsunamis.
4. Practice solving problems related to tsunami wave characteristics and propagation.
