    EVALUATION

    SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE
    BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER. FOR
    THOSE AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
    AFTER THE ESTIMATED TIME OF ARRIVAL 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.

    NO TSUNAMI THREAT EXISTS FOR OTHER COASTAL AREAS IN THE PACIFIC
    ALTHOUGH SOME OTHER AREAS MAY EXPERIENCE SMALL SEA LEVEL CHANGES.
    FOR ALL AREAS THE TSUNAMI WARNING AND TSUNAMI WATCH ARE
    CANCELLED.

    THIS WILL BE THE FINAL BULLETIN ISSUED FOR THIS EVENT UNLESS
    ADDITIONAL INFORMATION BECOMES AVAILABLE.

    THE JAPAN METEOROLOGICAL AGENCY MAY ALSO ISSUE TSUNAMI MESSAGES
    FOR THIS EVENT TO COUNTRIES IN THE NORTHWEST PACIFIC AND SOUTH
    CHINA SEA REGION. IN CASE OF CONFLICTING INFORMATION... THE
    MORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY.

    THE WEST COAST/ALASKA TSUNAMI WARNING CENTER WILL ISSUE BULLETINS
    FOR ALASKA - BRITISH COLUMBIA - WASHINGTON - OREGON - CALIFORNIA.
