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.THIS WILL BE THE FINAL BULLETIN ISSUED BY THE PACIFIC TSUNAMIWARNING CENTER FOR THIS EVENT UNLESS ADDITIONAL INFORMATIONBECOMES AVAILABLE.THE JAPAN METEOROLOGICAL AGENCY MAY ISSUE ADDITIONAL INFORMATIONFOR THIS EVENT. IN THE CASE OF CONFLICTING INFORMATION...THEMORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY. |
