M6.0 Earthquake 9 km W of Magsaysay, Philippines — February 7, 2021
2021-02-07 04:22:56 UTC (2021-02-07) · approx. 12:22 PM UTC+8 local
Felt by 77 people across nearby locations. Maximum shaking intensity MMI 7.5 (severe).
On February 7, 2021 at 04:22 UTC, a magnitude 6.0 shallow crustal earthquake struck 9 km W of Magsaysay, Philippines, at a depth of 16.0 km and coordinates 6.7693°, 125.1011°. The earthquake was reported felt by 77 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.5 (severe). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Dolo (population 3,973).
Physical scale: An earthquake of magnitude 6.0 releases seismic energy equivalent to roughly 15 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 8.3 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Philippines, a region characterized by the Manila Trench and Philippine Trench subduction systems, where the Philippine Sea Plate overrides the Eurasian Plate. The nearest mapped fault system is the Philippine Fault. View all earthquakes in Philippines.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 6.0 earthquakes can continue for weeks to months and gradually diminish over time.
Has Philippines had earthquakes this big before?
The largest recorded earthquake in Philippines was the M8.0 Mindanao earthquake of August 17, 1976. Today's magnitude 6.0 event is significantly smaller than that historical record.
