M5.7 Earthquake 21 km NNW of Bugko, Philippines — August 19, 2024
2024-08-19 03:39:01 UTC (2024-08-19) · approx. 11:39 AM UTC+8 local
Felt by 10 people across nearby locations. Maximum shaking intensity MMI 4.6 (moderate).
On August 19, 2024 at 03:39 UTC, a magnitude 5.7 shallow crustal earthquake struck 21 km NNW of Bugko, Philippines, at a depth of 48.0 km and coordinates 12.7182°, 124.7335°. The earthquake was reported felt by 10 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.6 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 111 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 505, placing it among routine seismic activity. The nearest populated place is Catarman (population 47,449).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 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 5.7 earthquakes can continue for days to weeks 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 5.7 event is significantly smaller than that historical record.
