Felt by 14 people across nearby locations.
On October 29, 2020 at 05:25 UTC, a magnitude 4.8 intermediate depth earthquake struck 1 km NW of Bagalangit, Philippines, at a depth of 76.9 km and coordinates 13.7177°, 120.8742°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
