EVALUATION
A WIDESPREAD DESTRUCTIVE TSUNAMI HAS OCCURRED, AND TSUNAMI WAVES
HAVE NOW CROSSED THE ENTIRE PACIFIC. FOR ALL 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. DUE TO LOCAL EFFECTS SOME AREAS MAY
CONTINUE TO EXPERIENCE SMALL SEA LEVEL CHANGES FOR AN EXTENDED
PERIOD LASTING HOURS OR EVEN DAYS.
FOR ALL AREAS COVERED BY THIS CENTER...THE TSUNAMI WARNING IS
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
