2024-10-14 23:42:51 UTC (2024-10-14) · approx. 7:42 AM UTC+8 local
On October 14, 2024 at 23:42 UTC, a magnitude 4.5 shallow crustal earthquake struck 89 km E of Aras-asan, Philippines, at a depth of 9.7 km and coordinates 8.7548°, 127.1148°. This earthquake was detected by 41 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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.
