MANILA—A 4.5-magnitude earthquake shook Cotabato province early Saturday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
The tectonic tremor occurred at a depth of 6 kilometers southeast of Tulunan town at 2:38 a.m.
Intensity 5, which can cause "strong" shaking, was recorded in Kidapawan City.
The state seismology bureau said this was part of the series of temblors that rocked parts of Mindanao in October.
The quakes have killed at least 17 people, wounded 327 others, displaced more than 30,000 people and damaged some 3,365 infrastructures, the National Disaster Risk Reduction and Management Council (NDRRMC) said in its Nov. 1 bulletin.
Phivolcs had said that Cotabato is one of the seismically active regions in the Philippines due to several active faults in the area: M’lang Fault, Makilala-Malungon Fault, North Columbio Fault, South Columbio Fault, and the western extension of the Mindanao Fault (Cotabato-Sindangan Fault).
