Shallow M5.5 earthquake hits Mindanao, Philippines
An earthquake of magnitude M5.5 was registered at 10:27 UTC on October 11, 2025, about 24 km (15 miles) east of Santiago, Philippines, at a depth of 60.1 km (37.4 miles).
The epicenter was located at 7.3°N, 126.8°E, placing the event in Mindanao, the second-largest island group in the Philippines, an area known for significant tectonic activity due to its proximity to major fault systems and subduction zones.
Critical infrastructure in this region may include local highways, inter-island ports, and regional airports, as well as energy and agricultural facilities common across Mindanao.
There is no tsunami threat associated with this earthquake, based on its location and available data.
Three felt reports were received for this event. The significance index is 467 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
The Philippines sit along the Pacific Ring of Fire, where the Philippine Sea Plate interacts with the Eurasian Plate and other smaller microplates, resulting in frequent seismic activity and major fault lines throughout the archipelago, particularly in Mindanao and the eastern provinces.
