Key information extracted from original GTS message :

Evaluation

It is not known that a TSUNAMI was generated
This warning is based only on the earthquake evaluation
An earthquake of this size has the potential to generate a destructive TSUNAMI that can strike coastlines in the region near the epicenter within minutes to hours
Authorities in the region should take appropriate action in response to this possibility
This center will monitor sea level gauges nearest the region and report if any TSUNAMI wave activity is observed
The warning will not expand to other areas of the pacific unless additional data are received to warrant such an expansion

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.

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
