IT IS NOT KNOWN THAT A TSUNAMI WAS GENERATED. THIS WARNING IS

STRIKE COASTLINES NEAR THE EPICENTER WITHIN MINUTES AND MORE
DISTANT COASTLINES WITHIN HOURS. AUTHORITIES SHOULD TAKE
APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS CENTER
WILL CONTINUE TO MONITOR SEA LEVEL DATA FROM GAUGES NEAR THE
EARTHQUAKE TO DETERMINE IF A TSUNAMI WAS GENERATED AND ESTIMATE
THE SEVERITY OF THE THREAT.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES. ACTUAL ARRIVAL TIMES
MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE LARGEST. THE TIME
BETWEEN SUCCESSIVE TSUNAMI WAVES CAN BE FIVE MINUTES TO ONE HOUR.
