Earthquakes in the United States — January 2025

6597 earthquakes were recorded in the United States during January 2025, an average of 212.8 per day.

33 reached magnitude 4 or above and 6 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 Nikolai, United States on 30 January 2025 at 04:40 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 7094 events over the period we cover, and down from the 9020 recorded the previous month.

96% of events here are shallow (under 70 km), 4% 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 10 in the magnitude -2 range, 373 in the magnitude -1 range, 1854 in the magnitude 0 range, 3288 in the magnitude 1 range, 922 in the magnitude 2 range, 117 in the magnitude 3 range.

Activity peaked on 02 January, when 358 events were recorded.

7 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 Nikolai, United States on 30 January at 0 km; M5.6 near Unalaska, United States on 26 January at 76 km; M5.2 near Rat Islands, Aleutian Islands, United States on 30 January at 102 km.

That is close to the 7094 events the United States averages per month across the 22 months on record.
