M3.6 Earthquake 67 km N of Yigo Village, Guam — August 24, 2026
2026-08-24 19:40:41 UTC (2026-08-24) · approx. 5:40 AM UTC+10 local
On August 24, 2026 at 19:40 UTC, a magnitude 3.6 intermediate depth earthquake struck 67 km N of Yigo Village, Guam, at a depth of 183.6 km and coordinates 14.1453°, 144.8654°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 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 5.3 mainshock that occurred 29 days ago 40 km NE of Yigo Village, Guam. Since the mainshock, the USGS has recorded 3 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 3.6 earthquake near Yigo Village, Guam?
The magnitude 3.6 earthquake that struck 67 km N of Yigo Village, Guam on August 24, 2026 at 19:40 UTC had a depth of 183.6 km. For context, this was a minor earthquake typically detected only by instruments.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 3.6 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.3 one earlier?
No. This magnitude 3.6 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 40 km NE of Yigo Village, Guam. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
