Recognize Tsunamis Natural Warning Signs
Big local earthquakes may cause tsunamis
FEEL the ground shaking severely, or for a long time?
A tsunami may be preceded by a rapid fall in sea level as the ocean recedes, exposing reefs, rocks, and fishes on the sea bottom.
Tsunami often comes ashore as a wall of water, and quickly flood inland.
SEE an unusual disappearance of water or oncoming wall of water?
Abnormal ocean activity, a wall of water, and approaching tsunami create a loud “roaring” sound similar to that of a train or jet aircraft.
HEAR the roar?
Don’t wait for official evacuation orders.
Immediately leave low-lying coastal areas.
Move inland to higher ground.
RUN if you see a tsunami coming!
