Key information extracted from original GTS message :

Evaluation Advisory

It is not known that a TSUNAMI was generated
This watch is based only on the earthquake evaluation
an earthquake of this size has the potential to generate a TSUNAMI that can strike coastlines with a wave height less than 0.5m and/or cause a TSUNAMI run-up less than 1m
Authorities should take appropriate action in response to this possibility
This center will monitor sea level data from gauges near the earthquake to determine if a TSUNAMI was generated and estimate the severity of the threat
A TSUNAMI is a series of waves and the first wave MAY not be the largest
TSUNAMI wave heights cannot be predicted and can vary significantly along a coast due to local effects
The time from one TSUNAMI wave to the next can be five minutes to an hour and the threat can continue for many hours as multiple waves arrive
