THOSE AREAS - WHEN DAMAGING WAVES HAVE NOT OCCURRED FOR AT LEAST
TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME THE THREAT IS PASSED.
DANGER TO BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR SEVERAL
HOURS DUE TO RAPID CURRENTS. AS LOCAL CONDITIONS CAN CAUSE A
WIDE VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION
MUST BE MADE BY LOCAL AUTHORITIES.
NO TSUNAMI THREAT EXISTS FOR OTHER COASTAL AREAS IN THE INDIAN
OCEAN ALTHOUGH SOME OTHER AREAS MAY EXPERIENCE SMALL SEA LEVEL
CHANGES AND STRONG OR UNUSUAL COASTAL CURRENTS.

WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
