Earthquakes and Tsunami Hazards

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

Some engineers want to see how different building designs might withstand a strong earthquake. What is the best way to determine this?

• Test one building during different earthquakes.

• Study past earthquake strengths on a graph.

• Test multiple model buildings for one model earthquake.

• Construct a real building to observe during an earthquake.

What is the main difference between the focus and the epicenter of an earthquake?

• The focus is the point on the surface, and the epicenter is below the surface.

• The focus is below the surface, and the epicenter is the point on the surface.

• The focus is where the earthquake is strongest, and the epicenter is where it is weakest.

• The focus is where the earthquake is weakest, and the epicenter is where it is strongest.
