Earthquakes in the U.S. Virgin Islands — January 2026

33 earthquakes were recorded in the U.S. Virgin Islands during January 2026, an average of 1.1 per day.

0 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 36 km.

The month's largest event in the U.S. Virgin Islands was a magnitude 3.7 earthquake near Cruz Bay, U.S. Virgin Islands on 05 January 2026 at 02:56 UTC. A magnitude 3.7 earthquake radiates roughly 6.1 tons of TNT equivalent in seismic energy.

That is close to the the U.S. Virgin Islands monthly average of 39 events over the period we cover, and up from the 13 recorded the previous month.

91% of events here are shallow (under 70 km), 9% 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 6 in the magnitude 2 range, 27 in the magnitude 3 range.

Activity peaked on 28 January, when 5 events were recorded.

The month's largest events were M3.7 near Cruz Bay, U.S. Virgin Islands on 05 January at 33 km; M3.7 near Cruz Bay, U.S. Virgin Islands on 23 January at 52 km; M3.7 near Charlotte Amalie, U.S. Virgin Islands on 20 January at 61 km.

That is 16% below the 39 events the U.S. Virgin Islands averages per month across the 21 months on record.
