Earthquakes in Russia — April 2025

12 earthquakes were recorded in Russia during April 2025, an average of 0.4 per day.

12 reached magnitude 4 or above and 3 reached magnitude 5 or above. The average focal depth was 84 km.

The month's largest event in Russia was a magnitude 5.4 earthquake near Ust’-Kamchatsk Staryy, Russia on 18 April 2025 at 18:41 UTC. A magnitude 5.4 earthquake radiates roughly 1,898 tons of TNT equivalent in seismic energy.

That is below the Russia monthly average of 90 events over the period we cover — a comparatively quiet month, and down from the 13 recorded the previous month.

67% of events here are shallow (under 70 km), 25% intermediate (70–300 km) and 8% deep-focus (over 300 km). That proportion of deep-focus events is the signature of a subduction zone: only a cold slab descending into the mantle stays brittle enough to rupture at those depths.

By band, the catalogue holds 9 in the magnitude 4 range, 3 in the magnitude 5 range.

Activity peaked on 18 April, when 2 events were recorded.

The month's largest events were M5.4 near Severo-Kuril’sk, Russia on 07 April at 51 km; M5.4 near Ust’-Kamchatsk Staryy, Russia on 18 April at 10 km; M5.3 near Severo-Kuril’sk, Russia on 24 April at 10 km.

That is 87% below the 90 events Russia averages per month across the 21 months on record.
