3) Tsunamis

• the Japanese word for “seismic sea wave.”

• triggered by an earthquake or landslide, travels very fast.

a. Tsunami Warning System

A seismic gap is an area along a fault where there has not been any earthquake activity for a long period of time.

III. Preparedness

If you live in an Earthquake prone area what things would you do to prevent loss of life or damage to
