M4.3 Earthquake 40 km SSW of Sarangani, Philippines — June 12, 2025
2025-06-12 19:23:09 UTC (2025-06-12) · approx. 3:23 AM UTC+8 local
On June 12, 2025 at 19:23 UTC, a magnitude 4.3 shallow crustal earthquake struck 40 km SSW of Sarangani, Philippines, at a depth of 40.9 km and coordinates 5.0960°, 125.2731°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 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 5.0 mainshock that occurred 20 hours ago 57 km S of Sarangani, Philippines. Since the mainshock, the USGS has recorded 3 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 4.3 earthquake near Sarangani, Philippines?
The magnitude 4.3 earthquake that struck 40 km SSW of Sarangani, Philippines on June 12, 2025 at 19:23 UTC had a depth of 40.9 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 4.3 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.0 one earlier?
No. This magnitude 4.3 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 57 km S of Sarangani, Philippines. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
