Earthquakes in the United States — January 2025

3474 earthquakes were recorded in the United States during January 2025, an average of 112.1 per day.

6 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 12 km.

The month's largest event in the United States was a magnitude 4.5 earthquake near Cobb, United States on 02 January 2025 at 02:34 UTC. A magnitude 4.5 earthquake radiates roughly 91 tons of TNT equivalent in seismic energy.

That is close to the the United States monthly average of 3650 events over the period we cover, and down from the 8253 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 2 in the magnitude -2 range, 242 in the magnitude -1 range, 925 in the magnitude 0 range, 1799 in the magnitude 1 range, 461 in the magnitude 2 range, 39 in the magnitude 3 range.

Activity peaked on 02 January, when 346 events were recorded.

1 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 M4.5 near Cobb, United States on 02 January at 1 km; M4.3 near Salt Flat, United States on 09 January at 10 km; M4.2 near Salt Flat, United States on 09 January at 6 km.

That is close to the 3650 events the United States averages per month across the 2 months on record.

This month also holds the strongest earthquake recorded in the United States in our entire catalogue.
