M7.4 Earthquake 12 km E of Santiago, Philippines — October 10, 2025
2025-10-10 01:43:59 UTC (2025-10-10) · approx. 9:43 AM UTC+8 local
Felt by 342 people across surrounding communities. Maximum shaking intensity MMI 7.4 (severe).
On October 10, 2025 at 01:43 UTC, a magnitude 7.4 shallow crustal earthquake struck 12 km E of Santiago, Philippines, at a depth of 59.4 km and coordinates 7.2866°, 126.6902°. The earthquake was reported felt by 342 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.4 (severe). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 291 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 1150, making it one of the most significant global earthquakes in recent days. The nearest populated place is Baculin (population 2,971).
Physical scale: An earthquake of magnitude 7.4 releases seismic energy equivalent to roughly 1.9 megatons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 77 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 7.4 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 7.4 event is within one magnitude unit of that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
