Sensing a Tsunami

Tsunamis can be detected using our human senses.

FEEL

Big local earthquakes may cause tsunamis

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 the roar?
