Understanding Tsunamis

What are the warning signs of a tsunami?

• Calm and still ocean surface

• Warning signs of a tsunami include rapid withdrawal of water, unusual ocean behavior, strong earthquakes, and a loud roar from the ocean.

• Consistent wave patterns

• Gentle breeze from the ocean

How is a tsunami formed?

• A tsunami occurs when large ships create waves in the ocean.

• A tsunami is formed by underwater disturbances that displace water, such as earthquakes or volcanic eruptions.

• A tsunami is caused by heavy rainfall flooding coastal areas.

• A tsunami is formed by the gravitational pull of the moon.

What is a tsunami?

• A tsunami is a tidal wave caused by the moon's gravitational pull.

• A tsunami is a type of underwater volcano.

• A tsunami is a single large wave that occurs during storms.

• A tsunami is a series of ocean waves caused by large disturbances in or near a body of water.

Which areas are most at risk for tsunamis?

• Mountainous regions away from oceans

• Deserts and arid regions

• Coastal areas near tectonic plate boundaries, especially the Pacific Ring of Fire.

• Inland areas far from coastlines

What should you do if you hear a tsunami warning?

• Stay where you are and wait for further instructions.

• Move to higher ground or inland immediately.

• Ignore the warning and continue your activities.

• Go to the beach to watch the waves.

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

• A tsunami is a type of tidal wave that happens during storms.

• A tsunami is caused by underwater disturbances; a tidal wave is related to gravitational forces affecting tides.

• A tsunami occurs only in oceans; a tidal wave can occur in rivers.

• A tsunami is a large wave caused by wind; a tidal wave is a small wave caused by rain.
