Key information extracted from original GTS message :
- Sea level readings confirm that a TSUNAMI was generated
- This TSUNAMI MAY have been destructive along coastlines of the region near the earthquake epicenter
- Authorities in the region should take appropriate action in response to this possibility
- This center will continue to monitor sea level gauges nearest the region and report if any additional TSUNAMI wave activity
- The warning will not expand to other areas of the pacific unless additional data are received to warrant such an expansion
- For affected areas - when no major waves are observed for two hours after the estimated time of arrival or damaging waves have not occurred for at least two hours then local authorities can assume the threat is passed
- Danger to boats and coastal structures can continue for several hours due to rapid currents
- As local conditions can cause a wide variation in TSUNAMI wave action the all clear determination must be made by local authorities
