A magnitude 6.7 earthquake shook Surigao del Sur and the rest of Mindanao at 3:49 a.m today, December 4, no tsunami threat in the Philippines according to PHIVOLCS. 

Hundreds of aftershocks were also recorded after the magnitude 6.7 earthquake occurred this morning, with a depth of 10 kilometers offshore of Surigao Del Sur. 

According to PHIVOLCS, a series of earthquakes were recorded with aftershocks occurring only minutes apart.

“It could be more than a thousand by now,” Labininay commented on the strong 3:39 am aftershock.

Aftershocks are common seismic occurrences, which take place after a stronger earthquake. They weaken in both intensity and frequency as time passes. 

PHIVOLCS’ data showed that the aftershock was strongly felt in the Caraga and Davao regions, and rattled residents as far as Cagayan de Oro in Northern Mindanao.  It was felt at Intensity IV in Nabunturan in Davao de Oro, Bislig City in Surigao del Sur, and Surigao City in Surigao del Norte.

Meanwhile, a magnitude 7.4 earthquake struck off the coast of Hinatuan, Surigao del Sur, on Saturday night, December 2 with 1 death reported. A tsunami warning was also raised by PHIVOLCS in Surigao del Sur after the earthquake happened. 

The earthquake impacted numerous regions of Mindanao, encompassing areas in Surigao del Sur and Agusan del Norte. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that the earthquake was tectonic and occurred at a depth of 25 kilometers.

According to a Facebook post, the local government of Hinatuan has ordered the “fast tracking of damage assessment.”
