AMPL - AMPLITUDE IN METERS FROM MIDDLE TO CREST

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.
