Earthquakes in Russia — August 2025

457 earthquakes were recorded in Russia during August 2025, an average of 14.7 per day.

457 reached magnitude 4 or above and 103 reached magnitude 5 or above. The average focal depth was 31 km.

The month's largest event in Russia was a magnitude 7.0 earthquake near Severo-Kuril’sk, Russia on 03 August 2025 at 05:37 UTC. A magnitude 7.0 earthquake radiates roughly 476,879 tons of TNT equivalent in seismic energy.

That is well above the Russia monthly average of 90 events over the period we cover — an unusually active month, and up from the 453 recorded the previous month.

92% of events here are shallow (under 70 km), 8% 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 354 in the magnitude 4 range, 96 in the magnitude 5 range, 6 in the magnitude 6 range, 1 in the magnitude 7 range.

Activity peaked on 01 August, when 70 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 M7.0 near Severo-Kuril’sk, Russia on 03 August at 41 km; M6.8 near Severo-Kuril’sk, Russia on 03 August at 35 km; M6.2 near Severo-Kuril’sk, Russia on 04 August at 10 km.

That is 407% above the 90 events Russia averages per month across the 21 months on record.
