On December 3, 2023 at 10:54 UTC, a magnitude 5.6 shallow crustal earthquake struck 61 km ENE of Hinatuan, Philippines, at a depth of 36.1 km and coordinates 8.5622°, 126.8620°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 94 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 482, placing it among routine seismic activity. The nearest populated place is Hinatuan (population 10,055).

Physical scale: An earthquake of magnitude 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 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 5.6 earthquakes can continue for days to weeks 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 5.6 event is significantly smaller than that historical record.
