2024-06-28 21:21:09 UTC (2024-06-28) · approx. 5:21 AM UTC+8 local
On June 28, 2024 at 21:21 UTC, a magnitude 4.8 shallow crustal earthquake struck 8 km WNW of Tibiao, Philippines, at a depth of 12.3 km and coordinates 11.3173°, 121.9609°. This earthquake was detected by 72 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
