Earthquakes in Micronesia

Micronesia appears infrequently in the record, with just 2 events in the past 30 days, and 13 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction. Activity here is almost entirely crustal, which means shaking at the surface is strong relative to the magnitudes involved.

25 earthquakes have been recorded in Micronesia in our catalogue, 2 of them in the past 30 days.

The average magnitude is 5.1 and the average focal depth 21 km. 25 events reached magnitude 4 or above and 13 reached magnitude 5 or above.

The strongest earthquake recorded in Micronesia in this period was a magnitude 5.9 event near State of Yap, Micronesia on 13 October 2025, at a depth of 10 km. A magnitude 5.9 earthquake radiates roughly 10,676 tons of TNT equivalent in seismic energy.

Locations recording the most events include Fais (13), Colonia (7).

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 12 in the magnitude 4 range, 13 in the magnitude 5 range.

The busiest single day was 17 August 2026, with 2 recorded events.

No event in this record carries a USGS link to NOAA tsunami information.
