At 14:11 PST (06:11 UTC) on December 15, 2019, the province of Davao del Sur on the island of Mindanao in the Philippines was struck by an earthquake measuring 6.8 Mww.

[8] 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.

[9][8] 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.

[9] The greatest damage from the earthquake was in the area around the epicenter, in the towns of Matanao, Magsaysay, Hagonoy and Padada.

Significant damage was reported in 207 out of 232 barangays in Davao del Sur, five in Sarangani, three in Sultan Kudarat and North Cotabato, respectively.

[7] A total of 5,973 houses were destroyed in Davao del Sur, with 31,832 suffering some damage and a further 32 in North Cotabato.

[13] Three hundred and ninety-seven schools and 62 health facilities were damaged in Davao del Sur, Sarangani and North Cotabato.
