Earthquakes in the United States — April 2026

8634 earthquakes were recorded in the United States during April 2026, an average of 287.8 per day.

71 reached magnitude 4 or above and 7 reached magnitude 5 or above. The average focal depth was 16 km.

The month's largest event in the United States was a magnitude 5.7 earthquake near Silver Springs, United States on 14 April 2026 at 01:29 UTC. A magnitude 5.7 earthquake radiates roughly 5,351 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 8825 recorded the previous month.

94% of events here are shallow (under 70 km), 6% 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 56 in the magnitude -2 range, 333 in the magnitude -1 range, 2093 in the magnitude 0 range, 4394 in the magnitude 1 range, 1415 in the magnitude 2 range, 272 in the magnitude 3 range.

Activity peaked on 14 April, when 451 events were recorded.

The month's largest events were M5.7 near Silver Springs, United States on 14 April at 10 km; M5.7 near Silver Springs, United States on 14 April at 5 km; M5.4 near Akutan, United States on 25 April at 35 km.

That is 20% above the 7168 events the United States averages per month across the 21 months on record.
