M5.2 Earthquake 29 km NNE of Santa Monica, Philippines — June 7, 2021
2021-06-07 21:41:10 UTC (2021-06-07) · approx. 5:41 AM UTC+8 local
On June 7, 2021 at 21:41 UTC, a magnitude 5.2 shallow crustal earthquake struck 29 km NNE of Santa Monica, Philippines, at a depth of 35.0 km and coordinates 10.2413°, 126.1873°.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
