natural 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.
