2023-06-14 18:08:51 UTC (2023-06-14) · approx. 2:08 AM UTC+8 local
On June 14, 2023 at 18:08 UTC, a magnitude 4.5 shallow crustal earthquake struck 242 km SSE of Sarangani, Philippines, at a depth of 49.8 km and coordinates 3.5269°, 126.5868°. This earthquake was detected by 37 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.
