Felt by 41 people across nearby locations.
On May 28, 2020 at 05:17 UTC, a magnitude 5.1 intermediate depth earthquake struck 6 km ESE of San Fernando, Philippines, at a depth of 77.5 km and coordinates 16.6027°, 120.3749°.
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.
