On December 17, 2023 at 10:58 UTC, a magnitude 4.9 shallow crustal earthquake struck 64 km ENE of Kinablangan, Philippines, at a depth of 59.1 km and coordinates 7.9923°, 127.0487°. This earthquake was detected by 96 seismic stations with good location accuracy and was assigned a USGS significance rating of 370, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
