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 CONFIRM THAT A TSUNAMI HAS BEEN GENERATED  WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE  APPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILL  CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND  SEVERITY OF THE THREAT.  A TSUNAMI IS A SERIES OF WAVES AND THE FIRST WAVE MAY NOT BE THE  LARGEST. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND CAN VARY  SIGNIFICANTLY ALONG A COAST DUE TO LOCAL EFFECTS. THE TIME FROM  ONE TSUNAMI WAVE TO THE NEXT CAN BE FIVE MINUTES TO AN HOUR, AND  THE THREAT CAN CONTINUE FOR MANY HOURS AS MULTIPLE WAVES ARRIVE.  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. BULLETINS WILL BE ISSUED HOURLY OR SOONER IF CONDITIONS WARRANT. THE TSUNAMI WARNING WILL REMAIN IN EFFECT UNTIL FURTHER NOTICE. 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.
