On November 11, 2026 at 08:37 UTC, a magnitude 4.7 intermediate depth earthquake struck 152 km WSW of Merizo Village, Guam, at a depth of 137.4 km and coordinates 12.8418°, 143.3322°. This earthquake was detected by 45 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — 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 5.4 mainshock that occurred 14 days ago 192 km WSW of Merizo Village, Guam. Since the mainshock, the USGS has recorded 0 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.7 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.4 one earlier?

No. This magnitude 4.7 earthquake is an aftershock of the larger magnitude 5.4 mainshock that occurred earlier 192 km WSW of Merizo Village, Guam. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
