M4.5 Earthquake 2 km ENE of Mangili, Philippines — June 25, 2022
2022-06-25 20:22:58 UTC (2022-06-25) · approx. 4:22 AM UTC+8 local
Aftershock of the M5.1 mainshock.
On June 25, 2022 at 20:22 UTC, a magnitude 4.5 intermediate depth earthquake struck 2 km ENE of Mangili, Philippines, at a depth of 150.5 km and coordinates 6.0116°, 125.7000°. This earthquake was detected by 54 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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 5.1 mainshock that occurred 28 days ago 19 km ENE of Lapuan, Philippines. Since the mainshock, the USGS has recorded 1 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 4.5 earthquake near Mangili, Philippines?
The magnitude 4.5 earthquake that struck 2 km ENE of Mangili, Philippines on June 25, 2022 at 20:22 UTC had a depth of 150.5 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 6.0116°, 125.7000°, which is 2 km ENE of Mangili, Philippines. View all earthquakes in Philippines.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.5 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.1 one earlier?
No. This magnitude 4.5 earthquake is an aftershock of the larger magnitude 5.1 mainshock that occurred earlier 19 km ENE of Lapuan, 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 4.5 event is significantly smaller than that historical record.
