HOWEVER AT SOME COASTS, PARTICULARLY THOSE NEAR THE EPICENTER, HIGHER

TSUNAMIS MAY ARRIVE THAN OUR ESTIMATION AT THE NEARBY

FORECAST POINTS

AUTHORITIES SHOULD BE AWARE OF THIS POSSIBILITY.



FURTHERMORE THE EVALUATION OF TSUNAMIGENIC POTENTIAL AND ESTIMATED

ARRIVAL TIME OF TSUNAMIS MAY BE DIFFERENT FROM THOSE OF PTWC

DUE TO DIFFERENCES IN THE ESTIMATED EARTHQUAKE PARAMETERS

AUTHORITIES SHOULD USE THE EARLIEST ARRIVAL TIMES FOR

GREATEST SAFETY.



THIS WILL BE THE FINAL BULLETIN UNLESS THERE ARE CHANGES ABOUT

THE POTENTIAL OF TSUNAMI GENERATION BY RE-EVALUATION OF THE

EARTHQUAKE OR THERE ARE REPORTS ON TSUNAMI OBSERVATIONS.
