Felt by 5 people across nearby locations.
On September 30, 2025 at 16:34 UTC, a magnitude 4.9 shallow crustal earthquake struck 17 km WSW of Villaba, Philippines, at a depth of 10.0 km and coordinates 11.1529°, 124.2400°. This earthquake was detected by 108 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 372, 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.
