Intensity VI was reached at Tacurong, Santo Niño in South Cotabato, and Digos in Davao del Sur.

A maximum perceived shaking of VII (PEIS) was reported from Tulunan, Makilala, Kidapawan City, Santa Cruz, Matanao, Magsaysay, Bansalan and Digos.

[43] Affected residents in Makilala, Cotabato were seen begging on the highway for basic needs such as rice and tents.

[44] The Cotabato sequence was followed by an earthquake, with a magnitude of Mw  6.8 (ANSS) or Ms  6.9 (PHIVOLCS), on December 15 at 14:11 PST with an epicenter in the neighboring province of Davao del Sur.

[25] InSAR interferograms can be used to detect and quantify ground deformation associated with an earthquake, allowing the location and orientation of fault ruptures, epicenters and slip distributions to be estimated.

[26][25] The two studies give similar results, confirming that the first and last major earthquakes in the sequence were caused by rupture along NW-SE trending left-lateral strike-slip faults, while the second and third resulted from rupture along SW-NE trending right-lateral strike-slip faults nearly orthogonal to the other two.
