M4.5 Earthquake 13 km SSW of Balangonan, Philippines — June 20, 2026
2026-06-20 14:05:21 UTC (3 hours ago) · approx. 10:05 PM UTC+8 local
Felt by 1 person across nearby locations. Aftershock of the M5.3 mainshock.
On June 20, 2026 at 14:05 UTC, a magnitude 4.5 shallow crustal earthquake struck 13 km SSW of Balangonan, Philippines, at a depth of 61.9 km and coordinates 5.4539°, 125.3179°. This earthquake was detected by 111 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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 5.3 mainshock that occurred 2 days ago 1 km S of Kablalan, Philippines. Since the mainshock, the USGS has recorded 10 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 4.5 earthquake near Balangonan, Philippines?
The magnitude 4.5 earthquake that struck 13 km SSW of Balangonan, Philippines on June 20, 2026 at 14:05 UTC had a depth of 61.9 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 5.4539°, 125.3179°, which is 13 km SSW of Balangonan, Philippines. View all earthquakes in Philippines.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.5 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.3 one earlier?
No. This magnitude 4.5 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 1 km S of Kablalan, 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 4.5 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.
