M4.9 Earthquake 55 km ESE of Baculin, Philippines — January 7, 2026
2026-01-07 13:47:59 UTC (2026-01-07) · approx. 9:47 PM UTC+8 local
Felt by 1 person across nearby locations. Aftershock of the M5.5 mainshock.
On January 7, 2026 at 13:47 UTC, a magnitude 4.9 shallow crustal earthquake struck 55 km ESE of Baculin, Philippines, at a depth of 35.5 km and coordinates 7.3431°, 127.0702°. This earthquake was detected by 173 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 370, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.5 mainshock that occurred 5 days ago 25 km ENE of Baganga, Philippines. Since the mainshock, the USGS has recorded 1 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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.

Common Questions
How strong was the magnitude 4.9 earthquake near Baculin, Philippines?
The magnitude 4.9 earthquake that struck 55 km ESE of Baculin, Philippines on January 7, 2026 at 13:47 UTC had a depth of 35.5 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 7.3431°, 127.0702°, which is 55 km ESE of Baculin, Philippines. View all earthquakes in Philippines.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.5 one earlier?
No. This magnitude 4.9 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier 25 km ENE of Baganga, Philippines. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 4.9 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.
