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

1 earthquakes were recorded in the U.S. Virgin Islands during September 2026, an average of 0.0 per day.

0 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 62 km.

The month's largest event in the U.S. Virgin Islands was a magnitude 3.2 earthquake near Cruz Bay, U.S. Virgin Islands on 01 September 2026 at 11:44 UTC. A magnitude 3.2 earthquake radiates roughly 1.1 tons of TNT equivalent in seismic energy.

That is below the the U.S. Virgin Islands monthly average of 38 events over the period we cover — a comparatively quiet month, and down from the 73 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 1 in the magnitude 3 range.

That is 97% below the 38 events the U.S. Virgin Islands averages per month across the 22 months on record.
