2024-07-19 06:19:31 UTC (2024-07-19) · approx. 2:19 PM UTC+8 local
On July 19, 2024 at 06:19 UTC, a magnitude 4.9 shallow crustal earthquake struck 31 km W of Gadung, Philippines, at a depth of 10.2 km and coordinates 6.8522°, 123.7377°. This earthquake was detected by 54 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
