Earthquakes in Micronesia — October 2025

4 earthquakes were recorded in Micronesia during October 2025, an average of 0.1 per day.

4 reached magnitude 4 or above and 4 reached magnitude 5 or above. The average focal depth was 10 km.

The month's largest event in Micronesia was a magnitude 5.9 earthquake near State of Yap, Micronesia on 13 October 2025 at 11:11 UTC. A magnitude 5.9 earthquake radiates roughly 10,676 tons of TNT equivalent in seismic energy.

That is well above the Micronesia monthly average of 2 events over the period we cover — an unusually active month, and up from the 3 recorded the previous month.

100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.

By band, the catalogue holds 4 in the magnitude 5 range.

Activity peaked on 10 October, when 2 events were recorded.

The month's largest events were M5.9 near State of Yap, Micronesia on 13 October at 10 km; M5.6 near Fais, Micronesia on 10 October at 10 km; M5.4 near Fais, Micronesia on 15 October at 10 km.

That is 108% above the 2 events Micronesia averages per month across the 13 months on record.

This month also holds the strongest earthquake recorded in Micronesia in our entire catalogue.
