    LAT – LATITUDE (N-NORTH, S-SOUTH)
    LON – LONGITUDE (E-EAST, W-WEST)
    TIME – TIME OF THE MEASUREMENT (Z IS UTC IS GREENWICH TIME)
    AMPL – TSUNAMI AMPLITUDE MEASURED RELATIVE TO NORMAL SEA LEVEL.
    IT IS …NOT… CREST-TO-TROUGH WAVE HEIGHT.
    VALUES ARE GIVEN IN BOTH METERS(M) AND FEET(FT).
    PER – PERIOD OF TIME IN MINUTES(MIN) FROM ONE WAVE TO THE NEXT.

    NOTE – DART MEASUREMENTS ARE FROM THE DEEP OCEAN AND THEY
    ARE GENERALLY MUCH SMALLER THAN WOULD BE COASTAL
    MEASUREMENTS AT SIMILAR LOCATIONS.

    EVALUATION

    SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY
    ALREADY HAVE BEEN DESTRUCTIVE ALONG SOME COASTS.

    BASED ON THESE DATA THE THREAT CONTINUES FOR ALL COASTAL AREAS OF
    THE INDIAN OCEAN. FOR THOSE AREAS – WHEN NO MAJOR WAVES HAVE
    OCCURRED FOR AT LEAST TWO HOURS AFTER THE ESTIMATED ARRIVAL TIME
    OR 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.

    ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
    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
    SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.
