Key information extracted from original GTS message :
- Sea level readings indicate a TSUNAMI was generated
- This TSUNAMI can strike coastlines with a wave height greather than 0.5m and/or cause a TSUNAMI run-up greater than 1m
- This center will continue to monitor sea level gauges nearest the region and report if any additional TSUNAMI wave activity is observed
- Authorities should take appropriate action in response to this possibility
- A TSUNAMI is a series of waves and the forst 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
