M4.2 Earthquake 4 km WSW of Talagutong, Philippines — October 15, 2025
2025-10-15 21:32:53 UTC (2025-10-15) · approx. 5:32 AM UTC+8 local
On October 15, 2025 at 21:32 UTC, a magnitude 4.2 intermediate depth earthquake struck 4 km WSW of Talagutong, Philippines, at a depth of 156.4 km and coordinates 6.2464°, 125.6335°.
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 5.1 mainshock that occurred 1 day ago 22 km ENE of Lapuan, Philippines. Since the mainshock, the USGS has recorded 0 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 4.2 earthquake near Talagutong, Philippines?
The magnitude 4.2 earthquake that struck 4 km WSW of Talagutong, Philippines on October 15, 2025 at 21:32 UTC had a depth of 156.4 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 M5.1 one earlier?
No. This magnitude 4.2 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 22 km ENE of Lapuan, Philippines. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
