Tsunami Flashcard

Front

What is a tsunami?

Back

A tsunami is a series of large ocean waves caused by disturbances such as earthquakes, volcanic eruptions, or meteorite impacts that displace a significant volume of water.

Front

What causes tsunamis?

Back

Tsunamis are primarily caused by underwater earthquakes, volcanic eruptions, landslides, or meteorite impacts that displace water.

Front

How fast can a tsunami travel in deep water?

Back

A tsunami can travel at speeds of up to 500 to 600 miles per hour (800 to 965 kilometers per hour) in deep water.

Front

What is the impact of a tsunami on coastal areas?

Back

Tsunamis can cause severe destruction to coastal areas, including the destruction of buildings, roads, and infrastructure, as well as loss of life.

Front

What are the long-term effects of tsunamis on communities?

Back

Long-term effects include loss of lives, destruction of infrastructure, displacement of people, economic decline, psychological trauma, and environmental damage.

Front

Can a tsunami be caused by a meteorite?

Back

TRUE - A meteorite impact in the ocean can displace water and generate a tsunami.

Front

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

Back

Tsunamis are caused by large-scale disturbances and can travel across entire ocean basins, while regular waves are generated by wind and are much smaller.

Front

What is the role of the seafloor in tsunami formation?

Back

The seafloor can uplift or subside during an earthquake, displacing a large volume of water and creating powerful tsunami waves.

Front

What safety measures can be taken during a tsunami warning?

Back

Safety measures include moving to higher ground, following evacuation orders, and staying away from the coast until the all-clear is given.

Front

What is a tsunami warning system?

Back

A tsunami warning system is a network of sensors and communication systems designed to detect tsunamis and alert communities at risk.
