"1. Severe ground shaking from local earthquakes may cause tsunamis.
2. As a tsunami approaches shorelines, water may recede from the coast, exposing the ocean floor, reefs and fish.
3.Abnormal ocean activity, a wall of water, and an approaching tsunami create a loud "roaring" sound similar to that of a train or jet aircraft.
If you experience any of these phenomena, don't wait for official evacuation orders. Immediately leave low-lying coastal areas and move to higher ground."
