On June 8, 2026 at 00:55 UTC, a magnitude 6.5 intermediate depth earthquake struck 18 km SW of Balangonan, Philippines, at a depth of 75.1 km and coordinates 5.4747°, 125.2173°. The earthquake was reported felt by 297 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.0 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 144 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 816, making it one of the more significant events of the week. The nearest populated place is Sarangani (population 22,515).

Physical scale: An earthquake of magnitude 6.5 releases seismic energy equivalent to roughly 85 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 18 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 6.5 earthquakes can continue for weeks to months 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 6.5 event is significantly smaller than that historical record.
