On August 5, 2026 at 21:41 UTC, a magnitude 5.9 shallow crustal earthquake struck 32 km SW of Sarangani, Philippines, at a depth of 10.0 km and coordinates 5.1757°, 125.2809°. The earthquake was reported felt by 3 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.2 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 84 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 536, placing it among routine seismic activity. The nearest populated place is Sarangani (population 22,515).

Physical scale: An earthquake of magnitude 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 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 6.3 mainshock that occurred 19 hours ago 32 km SW of Sarangani, Philippines. Since the mainshock, the USGS has recorded 9 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 5.9 earthquake near Sarangani, Philippines?

The magnitude 5.9 earthquake that struck 32 km SW of Sarangani, Philippines on August 5, 2026 at 21:41 UTC had a depth of 10.0 km. It was felt by 3 people with maximum shaking intensity of MMI 5.2 (strong). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 5.1757°, 125.2809°, which is 32 km SW 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 5.9 earthquakes can continue for days to weeks and gradually diminish over time.

Is this the same earthquake as the M6.3 one earlier?

No. This magnitude 5.9 earthquake is an aftershock of the larger magnitude 6.3 mainshock that occurred earlier 32 km SW 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 5.9 event is significantly smaller than that historical record.
