M4.6 Earthquake 10 km NNE of Kalbay, Philippines — June 17, 2025
2025-06-17 19:49:06 UTC (2025-06-17) · approx. 3:49 AM UTC+8 local
Felt by 2 people across nearby locations. Aftershock of the M5.1 mainshock.
On June 17, 2025 at 19:49 UTC, a magnitude 4.6 shallow crustal earthquake struck 10 km NNE of Kalbay, Philippines, at a depth of 67.4 km and coordinates 5.8112°, 125.5447°. This earthquake was detected by 78 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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 4 days ago 7 km WNW of Kalbay, Philippines. Since the mainshock, the USGS has recorded 8 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
The epicenter is located in Philippines, a region characterized by the Manila Trench and Philippine Trench subduction systems, where the Philippine Sea Plate overrides the Eurasian Plate. The nearest mapped fault system is the Philippine Fault. View all earthquakes in Philippines.

Common Questions
How strong was the magnitude 4.6 earthquake near Kalbay, Philippines?
The magnitude 4.6 earthquake that struck 10 km NNE of Kalbay, Philippines on June 17, 2025 at 19:49 UTC had a depth of 67.4 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 5.8112°, 125.5447°, which is 10 km NNE of Kalbay, Philippines. View all earthquakes in Philippines.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 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 4.6 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 7 km WNW of Kalbay, Philippines. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
Has Philippines had earthquakes this big before?
The largest recorded earthquake in Philippines was the M8.0 Mindanao earthquake of August 17, 1976. Today's magnitude 4.6 event is significantly smaller than that historical record.
