On June 7, 2026 at 23:37 UTC, a magnitude 7.8 shallow crustal earthquake struck 25 km SW of Kablalan, Philippines, at a depth of 57.0 km and coordinates 5.5994°, 125.0560°. The earthquake was reported felt by 577 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 8.5 (violent). The USGS PAGER system issued a orange alert level for this event, indicating regional impact possible. This earthquake was detected by 150 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 1525, making it one of the most significant global earthquakes in recent days. The nearest populated place is Maasin (population 64,940).

Physical scale: An earthquake of magnitude 7.8 releases seismic energy equivalent to roughly 7.6 megatons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 145 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 7.8 earthquakes can continue for months to years and gradually diminish over time.

Has Philippines had earthquakes this big before?

The largest recorded earthquake in Philippines was the M8.0 Mindanao earthquake of August 17, 1976. Today's magnitude 7.8 event is within one magnitude unit of that historical record.
