2021-11-09 22:36:35 UTC (2021-11-09) · approx. 6:36 AM UTC+8 local
On November 9, 2021 at 22:36 UTC, a magnitude 4.6 intermediate depth earthquake struck 59 km ESE of Caburan, Philippines, at a depth of 109.5 km and coordinates 5.6747°, 126.1207°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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.
