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
MORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY.

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