What U.S. Virgin Islands's numbers mean
U.S. Virgin Islands ranks 7th of 39 U.S. states and territories - a moderately active state.
- See U.S. Virgin Islands's computed risk level alongside every other state, using the same USGS-derived methodology. Open the risk calculator
- 75% of U.S. Virgin Islands's catalogued major earthquakes are shallow (under 70km) - shallow events generally produce stronger surface shaking than deep ones of the same magnitude. How depth affects shaking
- Compare U.S. Virgin Islands against every other U.S. state by count and maximum magnitude. See the full state ranking
Figures reflect the USGS ComCat catalog (M4+ since 2005, M6+ significant events since 1900) - not a real-time hazard assessment. For official guidance, see the USGS Earthquake Hazards Program.
According to the US Geological Survey Earthquake Hazards Program, PlainQuake's figures are rendered directly from 315,341 recorded M4+ earthquakes and 14,428 significant M6+ events (USGS ComCat, 2005-present) -- no figure is typed in by an editor.
