Earthquakes in the United States — February 2026

6467 earthquakes were recorded in the United States during February 2026, an average of 231.0 per day.

54 reached magnitude 4 or above and 7 reached magnitude 5 or above. The average focal depth was 15 km.

The month's largest event in the United States was a magnitude 6.3 earthquake near Nikolski, United States on 23 February 2026 at 05:11 UTC. A magnitude 6.3 earthquake radiates roughly 42,502 tons of TNT equivalent in seismic energy.

That is close to the the United States monthly average of 7168 events over the period we cover, and down from the 7965 recorded the previous month.

94% of events here are shallow (under 70 km), 6% 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 13 in the magnitude -2 range, 189 in the magnitude -1 range, 1424 in the magnitude 0 range, 3300 in the magnitude 1 range, 1265 in the magnitude 2 range, 221 in the magnitude 3 range.

Activity peaked on 12 February, when 294 events were recorded.

8 event(s) this month carry a USGS link to NOAA tsunami information; the flag does not indicate whether a tsunami occurred.

The month's largest events were M6.3 near Nikolski, United States on 23 February at 1 km; M6.1 near Nikolski, United States on 23 February at 14 km; M5.5 near Nikolski, United States on 23 February at 10 km.

That is close to the 7168 events the United States averages per month across the 21 months on record.
