M5.1 Earthquake 106 km E of Aras-asan, Philippines — December 10, 2023
2023-12-10 22:52:56 UTC (2023-12-10) · approx. 6:52 AM UTC+8 local
On December 10, 2023 at 22:52 UTC, a magnitude 5.1 shallow crustal earthquake struck 106 km E of Aras-asan, Philippines, at a depth of 10.0 km and coordinates 8.7373°, 127.2677°. This earthquake was detected by 152 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
