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

85 earthquakes were recorded in the U.S. Virgin Islands during February 2026, an average of 3.0 per day.

7 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 32 km.

The month's largest event in the U.S. Virgin Islands was a magnitude 4.5 earthquake near Cruz Bay, U.S. Virgin Islands on 09 February 2026 at 13:36 UTC. A magnitude 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.

That is well above the the U.S. Virgin Islands monthly average of 39 events over the period we cover — an unusually active month, and up from the 33 recorded the previous month.

99% of events here are shallow (under 70 km), 1% 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 16 in the magnitude 2 range, 62 in the magnitude 3 range, 7 in the magnitude 4 range.

Activity peaked on 09 February, when 37 events were recorded.

The month's largest events were M4.5 near Cruz Bay, U.S. Virgin Islands on 09 February at 32 km; M4.4 near Cruz Bay, U.S. Virgin Islands on 09 February at 27 km; M4.3 near Cruz Bay, U.S. Virgin Islands on 09 February at 49 km.

That is 116% above the 39 events the U.S. Virgin Islands averages per month across the 21 months on record.
