A magnitude 4.7 earthquake struck Saturday morning beneath the waters off Davao Occidental province in Mindanao but no damage has been reported and aftershocks are unlikely.
In its earthquake information 2 released Saturday, the state-run Philippine Institute of Volcanology and Seismology (Phivolcs) said the 10:38 a.m. offshore temblor of tectonic origin struck 113 km. south, 75 degrees east of Davao Occidental's Jose Abad Santos municipality at a depth of 56 km.
The earthquake was reported at intensity I in General Santos City, said Phivolcs.
Citing the earthquake's magnitude, Phivolcs said aftershocks are unlikely.
Phivolcs also said the earthquake struck far from land so damage is unlikely as well.
A local fault connected to the Philippine Fault Zone (PFZ) may have triggered the earthquake, noted Phivolcs.
PFZ is a 1,200 km.-long major tectonic feature transecting the Philippine archipelago from northwestern Luzon to southeastern Mindanao, Phivolcs added.
