EVALUATION
THIS EARTHQUAKE IS LOCATED OUTSIDE THE PACIFIC. NO TSUNAMI THREAT
EXISTS TO COASTLINES IN THE PACIFIC.
HOWEVER - EARTHQUAKES OF THIS SIZE SOMETIMES GENERATE LOCAL
TSUNAMIS THAT CAN BE DESTRUCTIVE ALONG COASTS LOCATED WITHIN
A FEW HUNDRED KILOMETERS OF THE EARTHQUAKE EPICENTER. AUTHORITIES
IN THE REGION OF THE EPICENTER SHOULD BE AWARE OF THIS
POSSIBILITY AND TAKE APPROPRIATE ACTION.
THIS CENTER MONITORS ONLY A LIMITED NUMBER OF SEA LEVEL GAUGES
OUTSIDE THE PACIFIC SO IT MAY NOT BE ABLE TO QUICKLY DETECT OR
MEASURE A TSUNAMI IF ONE WAS GENERATED. AUTHORITIES CAN ASSUME
THE DANGER HAS PASSED IF NO TSUNAMI WAVES ARE OBSERVED NEAR THE
EPICENTER WITHIN AN HOUR OF THE EARTHQUAKE.
THIS WILL BE THE ONLY 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.
