About This Ranking

This table ranks states by the number of notable earthquakes (generally M3.5+ for seismically active states, M2.5+ for quieter states) recorded by the USGS since 2004. States that hit the 100-event limit have even more recorded activity — the count shown is a floor, not a ceiling. A state with no qualifying event in that window is left out of the table rather than listed at zero — Minnesota is currently the only one.

Earthquake counts alone don't tell the full story. A state with fewer but larger earthquakes may face more risk than one with many small tremors. Use the address lookup tool above for location-specific risk assessment.
