On September 3, 2024 at 23:16 UTC, a magnitude 5.3 shallow crustal earthquake struck 28 km NE of Casuguran, Philippines, at a depth of 16.8 km and coordinates 14.8640°, 122.5951°. This earthquake was detected by 180 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 438, placing it among routine seismic activity.

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.
