Earthquakes in Russia — February 2025

15 earthquakes were recorded in Russia during February 2025, an average of 0.5 per day.

15 reached magnitude 4 or above and 4 reached magnitude 5 or above. The average focal depth was 58 km.

The month's largest event in Russia was a magnitude 5.8 earthquake near Ust’-Kamchatsk Staryy, Russia on 26 February 2025 at 16:15 UTC. A magnitude 5.8 earthquake radiates roughly 7,558 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 level with the 15 recorded the previous month.

80% of events here are shallow (under 70 km), 13% intermediate (70–300 km) and 7% 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 11 in the magnitude 4 range, 4 in the magnitude 5 range.

Activity peaked on 26 February, when 4 events were recorded.

The month's largest events were M5.8 near Ust’-Kamchatsk Staryy, Russia on 26 February at 10 km; M5.7 near Kosh-Agach, Russia on 15 February at 10 km; M5.2 near Tiksi, Russia on 28 February at 10 km.

That is 83% below the 90 events Russia averages per month across the 21 months on record.
