Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 6.9 occurred in the NEW britain region PAPUA NEW GUINEA at 2005 UTC on friday APRIL 4 2025
Based on all available data hazardous TSUNAMI waves are forecast for some coasts
We are waiting for data from the nearest tide gauge

Threat Forecast

TSUNAMI waves reaching 1 to 3 meters above the tide level are possible along some coasts of PAPUA NEW guinea.
TSUNAMI waves are forecast to be less than 0.3 meters above the tide level for the coasts of SOLOMON islands.
Actual amplitudes at the coast MAY vary from forecast amplitudes due to uncertainties in the forecast and local features. in particular maximum TSUNAMI amplitudes on atolls and at locations with fringing or barrier reefs will likely be much smaller than the forecast indicates.
For other areas covered by this product a forecast has not yet been computed. the forecast will be expanded if necessary in subsequent products.

Key information extracted from original GTS message :

Evaluation

There is a very small possibility of a destructive local TSUNAMI estimation at forecast points - no TSUNAMI waves with an amplitude of 0.3 meters or more are expected at any forecast point
However in some coastal areas (particularly near the epicenter) higher TSUNAMI waves than estimated MAY arrive
Authorities should be aware of this possibility
This will be the final bulletin unless changes in the potential for TSUNAMI generation are deemed possible based on earthquake re-evaluation or reports indicating TSUNAMI observation are received
