Key information extracted from original GTS message :
- 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
- Evaluation of TSUNAMI information based on historical earthquake and TSUNAMI modelling there is no threat that a TSUNAMI has been generated that can cause damage or major effect in the region
- This message is for information only
- However at some coasts particularly those near the epicenter higher tsunamis MAY arrive than our estimation
- Authorities should be aware of this possibility
