Earthquakes in Russia — September 2026

17 earthquakes were recorded in Russia during September 2026, an average of 0.6 per day.

17 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 84 km.

The month's largest event in Russia was a magnitude 5.5 earthquake near Kuril’sk, Russia on 04 September 2026 at 23:52 UTC. A magnitude 5.5 earthquake radiates roughly 2,682 tons of TNT equivalent in seismic energy.

That is below the Russia monthly average of 85 events over the period we cover — a comparatively quiet month, and down from the 36 recorded the previous month.

82% of events here are shallow (under 70 km), 6% intermediate (70–300 km) and 12% 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 15 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 29 September, when 2 events were recorded.

The month's largest events were M5.5 near Kuril’sk, Russia on 04 September at 32 km; M5.0 near Petropavlovsk-Kamchatsky, Russia on 30 September at 35 km; M4.9 near Petropavlovsk-Kamchatsky, Russia on 30 September at 32 km.

That is 80% below the 85 events Russia averages per month across the 23 months on record.
