2022-04-08 17:40:26 UTC (2022-04-08) · approx. 1:40 AM UTC+8 local
On April 8, 2022 at 17:40 UTC, a magnitude 4.5 shallow crustal earthquake struck 1 km NNW of Bagahanlad, Philippines, at a depth of 10.0 km and coordinates 12.5957°, 123.6625°.
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.
