Sensing a Tsunami

Tsunamis can be detected using our human senses.

Recognize a tsunami’s natural warning signs.

FEEL

Big local earthquakes may cause tsunamis
FEEL the ground shaking severely, or for a long time?

SEE

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?

HEAR

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?

RUN

Don’t wait for official evacuation orders
