M4.4 Earthquake 38 km WSW of Balangonan, Philippines — June 11, 2026
2026-06-11 21:57:07 UTC (2026-06-11) · approx. 5:57 AM UTC+8 local
On June 11, 2026 at 21:57 UTC, a magnitude 4.4 shallow crustal earthquake struck 38 km WSW of Balangonan, Philippines, at a depth of 35.0 km and coordinates 5.3881°, 125.0585°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 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 6.2 mainshock that occurred 3 days ago 32 km WSW of Sarangani, Philippines. Since the mainshock, the USGS has recorded 12 aftershocks in this area. Aftershock activity is expected to continue for weeks to months as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 4.4 earthquake near Balangonan, Philippines?
The magnitude 4.4 earthquake that struck 38 km WSW of Balangonan, Philippines on June 11, 2026 at 21:57 UTC had a depth of 35.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M6.2 one earlier?
No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 6.2 mainshock that occurred earlier 32 km WSW of Sarangani, Philippines. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
