M4.2 Earthquake 7 km S of Hukay, Philippines — June 12, 2026
2026-06-12 20:21:57 UTC (2026-06-12) · approx. 4:21 AM UTC+8 local
On June 12, 2026 at 20:21 UTC, a magnitude 4.2 intermediate depth earthquake struck 7 km S of Hukay, Philippines, at a depth of 202.1 km and coordinates 13.7796°, 120.6986°.
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 5.0 mainshock that occurred 10 days ago 7 km NW of Cabacao, 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 Hukay, Philippines?
The magnitude 4.2 earthquake that struck 7 km S of Hukay, Philippines on June 12, 2026 at 20:21 UTC had a depth of 202.1 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 M5.0 one earlier?
No. This magnitude 4.2 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 7 km NW of Cabacao, Philippines. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
