Earthquakes in the United States — February 2025

6664 earthquakes were recorded in the United States during February 2025, an average of 238.0 per day.

39 reached magnitude 4 or above and 5 reached magnitude 5 or above. The average focal depth was 13 km.

The month's largest event in the United States was a magnitude 5.8 earthquake near Akhiok, United States on 13 February 2025 at 23:59 UTC. A magnitude 5.8 earthquake radiates roughly 7,558 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 up from the 6597 recorded the previous month.

95% of events here are shallow (under 70 km), 5% 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 43 in the magnitude -2 range, 698 in the magnitude -1 range, 1900 in the magnitude 0 range, 3066 in the magnitude 1 range, 793 in the magnitude 2 range, 125 in the magnitude 3 range.

Activity peaked on 05 February, when 298 events were recorded.

4 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 M5.8 near Akhiok, United States on 13 February at 9 km; M5.0 near Adak, United States on 27 February at 131 km; M5.0 near Toyah, United States on 15 February at 7 km.

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