A seismograph can be used to measure and study what? 

• Volcanic eruptions
• Earthquakes
• Tsunamis
• All of the above

Scientists can predict EXACTLY when a volcanic eruption will occur.

• True

• False

Why is it beneficial to be able to predict when and where natural hazards will occur? 

• Communities can be notified to evacuate 
• So that we can stop them from happening again 
• So that scientists know where to go in order to study them 
• So that we can harness their power for renewable energy

How can some of the impacts of earthquakes be reduced?

• by building structures that can sway with the motion

• by building structures that do NOT move with the motion

• by using thermometers to measure ground temperatures

• by using satellites to monitor warning buoys in the ocean

• small earthquakes and gases in the air near the volcano

• increases in severe weather

Carlos's family lives close to an active volcano. What is the best way that he and his family can reduce the impact of an eruption and stay safe?

• Listen to the local news and follow evacuation instructions.

• Always wear masks to cover their mouths.

• Protect their home with lava-proof building materials.

• Evacuate when they see a lava flow reaching their home.
