2022-03-29 18:24:17 UTC (2022-03-29) · approx. 2:24 AM UTC+8 local
On March 29, 2022 at 18:24 UTC, a magnitude 4.9 shallow crustal earthquake struck 34 km W of Poblacion, San Felipe, Philippines, at a depth of 13.3 km and coordinates 15.0041°, 119.7519°.
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.
