The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has issued Tsunami Alert Level 3 in the following provinces: Northern Samar, Eastern Samar, Leyte, Southern Leyte, Surigao Del Norte and Surigao Del Sur. All these provinces are facing the Pacific Ocean in the east. People living near coastal areas in the said provinces are urged to evacuate immediately.
President Benigno Aquino III has ordered defense secretary Voltaire Gazmin, as concurrent head of the National Disaster Risk Reduction and Management Council “to monitor the tsunami in coordination with Phivolcs” and to “ensure that the affected PDRRMCs inform the local government officials and to further ensure that the evacuation in the affected areas be peaceful and orderly.”
NOTE: The website of PHIVOLCS is currently down. This was confirmed to me by Secretary Manolo Quezon via Twitter. When asked if there’s if there’s a possibility that the PHIVOLCS website can be fixed anytime soon, he said: “We will certainly look into this but let’s all concentrate on prompt advisories at this time.”
Netizens are using the hashtag #phtrenchquake for updates and advisories about this earthquake.
UPDATE, 11:30PM – Hawaii, United States-based Pacific Tsunami Warning Center (PTWC) has lifted its tsunami warning for the Philippines. However, the PTWC stressed in its report that “ONLY NATIONAL AND LOCAL GOVERNMENT AGENCIES HAVE THE AUTHORITY TO MAKE DECISIONS REGARDING THE OFFICIAL STATE OF ALERT IN THEIR AREA AND ANY ACTIONS TO BE TAKEN IN RESPONSE.” NDRRMC Executive Director Benito Ramos stressed that PHIVOLCS is yet to lift its tsunami warning for the abovementioned areas.
According to the PTWC, when no major waves are observed two hours after those were expected to arrive, local authorities can assume that the danger has passed. It also warned that boats and coastal structures will remain in danger for the next several hours because of rapid currents.
