Chapter 4: Tsunami Warning Systems Quiz

What is the purpose of tsunami warning systems?

• To measure earthquakes and changes in the ocean

• To install and maintain sensors

• To issue evacuation warnings to affected locations

• To detect local tsunami waves

Why are tsunami warning systems important for ocean-wide tsunamis?

• Because ocean-wide tsunamis can travel to locations across the ocean

• Because ocean-wide tsunamis are more dangerous than local tsunamis

• Because people living on the other side of the ocean cannot feel the earthquake

• Because people living near the ocean can feel the earthquake

How do tsunami warning centers evaluate whether to issue warnings?

• By sending evacuation warnings to all locations

• By waiting for data from additional sensors

• By collecting data from earthquake sensors

• By considering the reliability of the data received
