Earthquakes in the United States — June 2025

7575 earthquakes were recorded in the United States during June 2025, an average of 252.5 per day.

27 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 12 km.

The month's largest event in the United States was a magnitude 5.2 earthquake near Nikolski, United States on 28 June 2025 at 06:08 UTC. A magnitude 5.2 earthquake radiates roughly 951 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 6805 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 4 in the magnitude -2 range, 428 in the magnitude -1 range, 2509 in the magnitude 0 range, 3504 in the magnitude 1 range, 949 in the magnitude 2 range, 154 in the magnitude 3 range.

Activity peaked on 06 June, when 320 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 M5.2 near Nikolski, United States on 28 June at 10 km; M5.0 near Adak, United States on 03 June at 15 km; M4.9 near Attu Station, United States on 29 June at 85 km.

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