On February 7, 2021, at 12:22 PM PST, an earthquake measuring Mww 6.0 struck Davao del Sur and Cotabato.
It was first recorded as magnitude 6.3 by the Philippine Institute of Volcanology and Seismology, which later downgraded it to Mw 6.1 at a shallow depth of 10 km.
There was a foreshock which preceded the main quake, recorded Mw 4.8 at 7:28 AM PST by Philippine Institute of Volcanology and Seismology with a PHIVOLCS Earthquake Intensity Scale of IV (Moderately Strong).
These faults may work with subduction zones to accommodate different components of regional tectonic strain in the slip partitioning system caused by the relative motion between the PSP and SP.
Characterizing the geometrical complexity of these source faults has great significance for understanding the seismotectonic implications of the large earthquakes occurring in Mindanao.
[7] National Disaster Risk Reduction and Management Council teams and Engineers immediately conducted damage inspection to buildings and houses and casualties.
At least seven landslides were reported in Makilala,[8] and cracks as long as 5–10 meters found their way to the floors of houses, while some walls collapsed at Sitio B'yao, New Esperanza village of M'lang.
