Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 7.4 occurred in mindanao PHILIPPINES at 0144 UTC on friday OCTOBER 10 2025
Based on all available data hazardous TSUNAMI waves are forecast for some coasts

Threat Forecast

TSUNAMI waves reaching 1 to 3 meters above the tide level are possible along some coasts of philippines.
TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of indonesia... and palau.
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.
