UNDISTURBED SEA LEVEL TO THE CREST



IN SOME COASTAL AREAS (PARTICULARLY NEAR THE EPICENTER),

TSUNAMI WAVES MAY BE HIGHER AND/OR ARRIVE EARLIER THAN

ESTIMATED FOR NEARBY FORECAST POINTS.

AUTHORITIES SHOULD BE AWARE OF THIS POSSIBILITY.



THE EVALUATION OF TSUNAMIGENIC POTENTIAL AND ESTIMATED

ARRIVAL TIMES FOR TSUNAMI WAVES MAY ALSO DIFFER FROM

THOSE OF PTWC DUE TO DIFFERENCES IN ESTIMATED EARTHQUAKE

PARAMETERS AND THE TSUNAMI FORECAST MODEL.

AUTHORITIES SHOULD REFER TO EARLIER ARRIVAL TIMES

FOR GREATEST SAFETY.



THIS WILL BE THE FINAL BULLETIN UNLESS CHANGES IN THE POTENTIAL

FOR TSUNAMI GENERATION ARE DEEMED POSSIBLE BASED ON EARTHQUAKE

RE-EVALUATION OR REPORTS INDICATING TSUNAMI OBSERVATION ARE

RECEIVED.
