On November 6, 2026 at 22:37 UTC, a magnitude 4.6 intermediate depth earthquake struck 11 km ENE of Yigo Village, Guam, at a depth of 113.4 km and coordinates 13.5679°, 144.9932°. This earthquake was detected by 43 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 327, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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 28 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 4.6 earthquake near Yigo Village, Guam?

The magnitude 4.6 earthquake that struck 11 km ENE of Yigo Village, Guam on November 6, 2026 at 22:37 UTC had a depth of 113.4 km. For context, this was a light earthquake commonly felt near the epicenter.

Where did the earthquake occur?

The earthquake epicenter was located at 13.5679°, 144.9932°, which is 11 km ENE of Yigo Village, Guam.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.6 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 4.6 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.
