CH 8 Earthquakes

The strongest earthquakes usually occur

• near divergent boundaries.

• near convergent boundaries.

• near transform boundaries.

• along normal faults.

Studying earthquake waves currently allows seismologists to do all of the following EXCEPT

• determine when an earthquake started.

• learn about the Earth's interior.

• decrease an earthquake's strength.

• determine where an earthquake started.

• change direction as they travel through the core.

• cannot pass through the core.
