Tsunamialarm afgekondigd na krachtige aardbeving nabij Salomonseilanden

Een aardbeving met een kracht van 7,6 op de schaal van Richter heeft zaterdagavond de Salomonseilanden, in de Stille Oceaan, getroffen. In het gebied is een tsunamialarm afgekondigd, zo melden internationale media. Volgens het Amerikaans geofysisch instituut USGS lag het epicentrum van de beving een kleine honderd kilometer ten zuidoosten van de eilandengroep. De haard bevond zich op een diepte van zowat tien kilometer. De tsunamiwaarschuwing geldt niet enkel voor de Salomonseilanden, maar ook voor Papoea-Nieuw-Guinea, Vanuatu en Nauru. Ook in Guam, Australië, Nieuw-Zeeland en Amerikaans-Samoa wordt opgeroepen om alert te blijven voor een eventuele tsunami, zo meldt CNN op zijn website.

Inmiddels is het tsunamialarm weer ingetrokken.

EVALUATION

SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE  BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER. FOR THOSE 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.

NO TSUNAMI THREAT EXISTS FOR OTHER COASTAL AREAS IN THE PACIFIC ALTHOUGH SOME OTHER AREAS MAY EXPERIENCE SMALL SEA LEVEL CHANGES. THE TSUNAMI WARNING IS NOW CANCELLED FOR ALL AREAS COVERED BY THIS CENTER.
