M6.4 Earthquake 35 km E of Santiago, Philippines — January 7, 2026
2026-01-07 03:02:53 UTC (2026-01-07) · approx. 11:02 AM UTC+8 local
Felt by 35 people across nearby locations. Maximum shaking intensity MMI 6.2 (very strong).
On January 7, 2026 at 03:02 UTC, a magnitude 6.4 shallow crustal earthquake struck 35 km E of Santiago, Philippines, at a depth of 22.0 km and coordinates 7.2449°, 126.8953°. The earthquake was reported felt by 35 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.2 (very 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 160 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 648, making it a moderate-impact event. The nearest populated place is Baculin (population 2,971).
Physical scale: An earthquake of magnitude 6.4 releases seismic energy equivalent to roughly 60 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 16 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 6.4 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 6.4 event is significantly smaller than 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.
