On July 11, 2024 at 02:13 UTC, a magnitude 7.1 deep-focus earthquake struck 106 km WSW of Sangay, Philippines, at a depth of 639.5 km and coordinates 6.0838°, 123.1503°. The earthquake was reported felt by 29 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.3 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 401 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 790, making it a moderate-impact event. The nearest populated place is Katidtuan (population 4,710).

Physical scale: An earthquake of magnitude 7.1 releases seismic energy equivalent to roughly 674 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 48 km — a useful intuition for the size of the slip patch on the fault.

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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 7.1 earthquakes can continue for months to years and gradually diminish over time.

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 7.1 event is within one magnitude unit of that historical record.
