WARNING... THIS EARTHQUAKE HAS THE POTENTIAL TO GENERATE A WIDELY
DESTRUCTIVE TSUNAMI IN THE OCEAN OR SEAS NEAR THE EARTHQUAKE.
AUTHORITIES IN THOSE REGIONS SHOULD BE AWARE OF THIS POSSIBILITY
AND TAKE IMMEDIATE ACTION. THIS ACTION SHOULD INCLUDE EVACUATION
OF COASTS WITHIN A THOUSAND KILOMETERS OF THE EPICENTER AND CLOSE
MONITORING TO DETERMINE THE NEED FOR EVACUATION FURTHER AWAY.

GENERATED. AUTHORITIES CAN ASSUME THE DANGER HAS PASSED IF NO
TSUNAMI WAVES ARE OBSERVED IN THE REGION NEAR THE EPICENTER
WITHIN THREE HOURS OF THE EARTHQUAKE.
