On June 26, 2026 at 22:11 UTC, a magnitude 4.2 shallow crustal earthquake struck 76 km SW of Balangonan, Philippines, at a depth of 9.2 km and coordinates 5.1699°, 124.7906°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 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 9 days ago 32 km WSW of Sarangani, Philippines. Since the mainshock, the USGS has recorded 10 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 4.2 earthquake near Balangonan, Philippines?

The magnitude 4.2 earthquake that struck 76 km SW of Balangonan, Philippines on June 26, 2026 at 22:11 UTC had a depth of 9.2 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 4.2 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 4.2 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.

Understanding This Data

Magnitude 4.2 earthquakes are often felt but rarely cause damage.
