Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 7.0 occurred in the SOLOMON ISLANDS at 1910 UTC on friday december 9 2016
TSUNAMI waves have been observed
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 SOLOMON islands.
TSUNAMI waves are forecast to be much less than 0.3 meters above the tide level elsewhere.
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.
