2022-01-30 00:17:12 UTC (2022-01-30) · approx. 8:17 AM UTC+8 local
On January 30, 2022 at 00:17 UTC, a magnitude 5.3 shallow crustal earthquake struck 167 km WSW of Ilioilio, Philippines, at a depth of 10.0 km and coordinates 15.6262°, 118.2370°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
