Earthquakes in the United States — October 2025

6522 earthquakes were recorded in the United States during October 2025, an average of 210.4 per day.

31 reached magnitude 4 or above and 6 reached magnitude 5 or above. The average focal depth was 14 km.

The month's largest event in the United States was a magnitude 5.4 earthquake near Fox River, United States on 30 October 2025 at 17:33 UTC. A magnitude 5.4 earthquake radiates roughly 1,898 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 7343 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 6 in the magnitude -2 range, 274 in the magnitude -1 range, 1654 in the magnitude 0 range, 3516 in the magnitude 1 range, 926 in the magnitude 2 range, 115 in the magnitude 3 range.

Activity peaked on 07 October, when 296 events were recorded.

5 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 M5.4 near Fox River, United States on 30 October at 24 km; M5.4 near off the coast of Oregon, United States on 29 October at 10 km; M5.1 near Akutan, United States on 17 October at 76 km.

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