Earthquakes in the U.S. Virgin Islands — June 2025

24 earthquakes were recorded in the U.S. Virgin Islands during June 2025, an average of 0.8 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 3.8 earthquake near Charlotte Amalie, U.S. Virgin Islands on 06 June 2025 at 03:04 UTC. A magnitude 3.8 earthquake radiates roughly 8.7 tons of TNT equivalent in seismic energy.

That is below the the U.S. Virgin Islands monthly average of 39 events over the period we cover — a comparatively quiet month, and down from the 32 recorded the previous month.

92% of events here are shallow (under 70 km), 8% 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, 18 in the magnitude 3 range.

Activity peaked on 16 June, when 6 events were recorded.

The month's largest events were M3.8 near Charlotte Amalie, U.S. Virgin Islands on 06 June at 35 km; M3.8 near Cruz Bay, U.S. Virgin Islands on 21 June at 49 km; M3.8 near Cruz Bay, U.S. Virgin Islands on 27 June at 11 km.

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