Earthquakes in the United States — April 2025

7432 earthquakes were recorded in the United States during April 2025, an average of 247.7 per day.

29 reached magnitude 4 or above and 8 reached magnitude 5 or above. The average focal depth was 14 km.

The month's largest event in the United States was a magnitude 6.0 earthquake near San Diego Country Estates, United States on 14 April 2025 at 17:08 UTC. A magnitude 6.0 earthquake radiates roughly 15,080 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 7185 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, 342 in the magnitude -1 range, 2530 in the magnitude 0 range, 3518 in the magnitude 1 range, 890 in the magnitude 2 range, 117 in the magnitude 3 range.

Activity peaked on 14 April, when 425 events were recorded.

16 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 M6.0 near San Diego Country Estates, United States on 14 April at 9 km; M5.5 near Attu Station, United States on 02 April at 12 km; M5.3 near Attu Station, United States on 02 April at 40 km.

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