M5.0 Earthquake 68 km ESE of Bobon, Philippines — June 17, 2026
2026-06-17 21:49:26 UTC (1 hour ago) · approx. 5:49 AM UTC+8 local
Aftershock of the M6.2 mainshock.
On June 17, 2026 at 21:49 UTC, a magnitude 5.0 shallow crustal earthquake struck 68 km ESE of Bobon, Philippines, at a depth of 36.1 km and coordinates 6.5857°, 126.8825°. This earthquake was detected by 22 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — 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 2 days ago 67 km ESE of Pondaguitan, Philippines. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for weeks to months 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 5.0 earthquake near Bobon, Philippines?
The magnitude 5.0 earthquake that struck 68 km ESE of Bobon, Philippines on June 17, 2026 at 21:49 UTC had a depth of 36.1 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 6.5857°, 126.8825°, which is 68 km ESE of Bobon, Philippines. View all earthquakes in Philippines.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M6.2 one earlier?
No. This magnitude 5.0 earthquake is an aftershock of the larger magnitude 6.2 mainshock that occurred earlier 67 km ESE of Pondaguitan, 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 5.0 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
