2025-10-17 08:31:48 UTC (2025-10-17) · approx. 4:31 PM UTC+8 local
On October 17, 2025 at 08:31 UTC, a magnitude 4.9 shallow crustal earthquake struck 15 km N of Davila, Philippines, at a depth of 14.1 km and coordinates 18.6114°, 120.5524°. This earthquake was detected by 49 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, 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.
