On November 17th, 2023, at 4:14 PM local time, a powerful earthquake struck the municipality of Sarangani in Davao Occidental, Mindanao, with a magnitude of 6.8 on the Richter scale.
The epicenter was located 28 kilometers southwest of Sarangani, with a depth of 63 kilometers. The earthquake was likely caused by the Cotabato Trench, and was felt throughout a large portion of Mindanao. In the following 14 hours, the DOST-PHIVOLCS Philippine Seismic Network recorded 58 aftershocks ranging from 1.4 to 3.9 magnitude.
The damage of 6.8 magnitude earthquake
According to the DOST-PHIVOLCS Earthquake Information 4 (Annex 1), the highest intensity reported using the PHIVOLCS Earthquake Intensity Scale (PEIS) was PEIS VII (Destructive) in Glan, Sarangani.
At this intensity level, many people are likely to be frightened and may seek safety outdoors. Heavy objects and furniture may be overturned or toppled, and large church bells may ring.
Old or poorly-constructed buildings may sustain significant damage, while some well-built structures may experience minor damage. Cracks may appear on dikes, fish ponds, road surfaces, or concrete hollow block walls.
Additionally, limited liquefaction, lateral spreading, and landslides may occur. Trees are also likely to be shaken strongly.
According to reports, over 1,500 families have been affected, with their homes either damaged or their sources of income disrupted, across the province. The Glan Municipal Hall sustained significant damage and has been deemed unfit for occupation.
