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
