2020-11-04 18:27:48 UTC (2020-11-04) · approx. 2:27 AM UTC+8 local
On November 4, 2020 at 18:27 UTC, a magnitude 5.0 shallow crustal earthquake struck 5 km NW of Santa Monica, Philippines, at a depth of 55.9 km and coordinates 10.0607°, 126.0084°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
