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 greater than 0.5m and/or cause a TSUNAMI run-up greater 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 however at some coasts particularly those near the epicenter higher tsunamis MAY arrive than our estimation
- Authorities should be aware of this possibility
