NOTE - DART MEASUREMENTS ARE FROM THE DEEP OCEAN AND THEYARE GENERALLY MUCH SMALLER THAN WOULD BE COASTALMEASUREMENTS AT SIMILAR LOCATIONS. EVALUATION SEA LEVEL READINGS CONFIRM THAT A TSUNAMI HAS BEEN GENERATEDWHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKEAPPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILLCONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT ANDSEVERITY OF THE THREAT. A TSUNAMI IS A SERIES OF WAVES AND THE FIRST WAVE MAY NOT BE THELARGEST. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND CAN VARYSIGNIFICANTLY ALONG A COAST DUE TO LOCAL EFFECTS. THE TIME FROMONE TSUNAMI WAVE TO THE NEXT CAN BE FIVE MINUTES TO AN HOUR, ANDTHE THREAT CAN CONTINUE FOR MANY HOURS AS MULTIPLE WAVES ARRIVE. FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURSAFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOTOCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUMETHE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CANCONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCALCONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THEALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES. ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTSWITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUALARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THELARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEENSUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.
