How does an earthquake generate a tsunami?

Back

When an earthquake occurs under the ocean, it displaces a large volume of water, creating waves that can travel across the ocean.

Front

What are the characteristics of a tsunami wave?

Back

Tsunami waves have long wavelengths, can travel at high speeds in deep water, and can grow in height as they approach shallow coastal areas.

Front

What is the difference between a tsunami and a regular ocean wave?

Back

Tsunamis are caused by geological events and can travel across entire ocean basins, while regular waves are generated by wind and are limited to the surface.

Front

What role do volcanic eruptions play in tsunamis?

Back

Volcanic eruptions can displace water and create tsunamis, especially if the eruption involves the collapse of a volcanic island or the explosion of an underwater volcano.

Front

What is the term for the point where a tsunami originates?

Back

The epicenter.

Front

What is the impact of a tsunami on coastal areas?

Back

Tsunamis can cause devastating flooding, destruction of infrastructure, and loss of life in coastal areas.

Front

How can tsunamis be detected?

Back

Tsunamis can be detected using seismic monitoring systems and ocean buoys that measure changes in sea level.

Front

What safety measures should be taken during a tsunami warning?

Back

People should evacuate to higher ground, avoid coastal areas, and follow instructions from local authorities.
