Key information extracted from original GTS message :

Evaluation

There is a very small possibility of a destructive local TSUNAMI estimation at forecast points - no TSUNAMI waves with an amplitude of 0.3 meters or more are expected at any forecast point
However in some coastal areas (particularly near the epicenter) higher TSUNAMI waves than estimated MAY arrive
Authorities should be aware of this possibility
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
