Understanding the Powerful Waves of Tsunamis

A tsunami is a large wave caused by the displacement of water due to events like earthquakes, volcanic eruptions, or underwater explosions. These waves can be much larger than normal ocean waves and are often catastrophic. Tsunamis have long wavelengths and can travel quickly, increasing in height as they approach shorelines. A drawback, or receding shoreline, is a warning sign of an incoming tsunami. Safety measures include moving to higher ground. Tsunami prediction is challenging, but systems with pressure sensors and expert analysis can provide warnings.

What natural events can lead to the formation of a tsunami?

• Droughts and heatwaves

• Hurricanes and tornadoes

• Earthquakes and volcanic eruptions

• Tidal changes due to the moon

What is the literal translation of the word 'tsunami'?

• Ocean wave

• Sea storm

• Harbor wave

• Water surge

How do tsunami waves differ from normal ocean waves?

• They have longer wavelengths

• They are shorter in length

• They are slower in speed

• They are caused by wind

What happens to the shoreline during a tsunami drawback?

• It remains unchanged

• It becomes more elevated

• It recedes dramatically

• It gets covered with debris

What is a recommended action if a tsunami drawback is observed?

• Wait for further instructions

• Stay on the beach

• Go swimming

• Run for high ground
