M5.5 Earthquake 2 km SSW of Sarangani, Philippines — June 8, 2026
2026-06-08 05:12:04 UTC (45 min ago) · approx. 1:12 PM UTC+8 local
Maximum shaking intensity MMI 5.0 (strong). Aftershock of the M5.8 mainshock.
On June 8, 2026 at 05:12 UTC, a magnitude 5.5 shallow crustal earthquake struck 2 km SSW of Sarangani, Philippines, at a depth of 51.1 km and coordinates 5.3774°, 125.4566°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 81 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 465, placing it among routine seismic activity. The nearest populated place is Sarangani (population 22,515).
Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 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 5.8 mainshock that occurred 4 hours ago 11 km SE of Sarangani, Philippines. Since the mainshock, the USGS has recorded 2 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 5.5 earthquake near Sarangani, Philippines?
The magnitude 5.5 earthquake that struck 2 km SSW of Sarangani, Philippines on June 8, 2026 at 05:12 UTC had a depth of 51.1 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 5.3774°, 125.4566°, which is 2 km SSW of Sarangani, Philippines. The nearest populated place is Sarangani (population 22,515). View all earthquakes in Philippines.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.5 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.8 one earlier?
No. This magnitude 5.5 earthquake is an aftershock of the larger magnitude 5.8 mainshock that occurred earlier 11 km SE of Sarangani, 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 5.5 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.
