2024-02-01 21:35:39 UTC (2024-02-01) · approx. 5:35 AM UTC+8 local
On February 1, 2024 at 21:35 UTC, a magnitude 5.1 shallow crustal earthquake struck 51 km E of Barcelona, Philippines, at a depth of 62.5 km and coordinates 8.1667°, 126.9026°. This earthquake was detected by 92 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
