The month's largest event in Guam was a magnitude 5.9 earthquake near Merizo Village, Guam on 04 November 2025 at 07:37 UTC. A magnitude 5.9 earthquake radiates roughly 10,676 tons of TNT equivalent in seismic energy.

20% of events here are shallow (under 70 km), 80% intermediate (70–300 km) and 0% deep-focus (over 300 km). A substantial share of intermediate-depth events points to a subducting slab beneath the region rather than purely crustal faulting.
By band, the catalogue holds 3 in the magnitude 4 range, 2 in the magnitude 5 range.
The month's largest events were M5.9 near Merizo Village, Guam on 04 November at 66 km; M5.4 near Yigo Village, Guam on 09 November at 103 km; M4.8 near Dededo Village, Guam on 05 November at 110 km.
