2022-03-12 22:11:00 UTC (2022-03-12) · approx. 6:11 AM UTC+8 local
On March 12, 2022 at 22:11 UTC, a magnitude 4.5 shallow crustal earthquake struck 172 km SSE of Pondaguitan, Philippines, at a depth of 56.3 km and coordinates 5.0401°, 127.0089°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
