Earthquakes in Norway — October 2025
3 earthquakes were recorded in Norway during October 2025, an average of 0.1 per day.
3 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 10 km.
The month's largest event in Norway was a magnitude 5.2 earthquake near Olonkinbyen, Norway on 05 October 2025 at 09:08 UTC. A magnitude 5.2 earthquake radiates roughly 951 tons of TNT equivalent in seismic energy.
That is well above the Norway monthly average of 2 events over the period we cover — an unusually active month, and up from the 1 recorded the previous month.
100% of events here are shallow (under 70 km), 0% 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 2 in the magnitude 4 range, 1 in the magnitude 5 range.
Activity peaked on 05 October, when 3 events were recorded.
The month's largest events were M5.2 near Olonkinbyen, Norway on 05 October at 10 km; M4.8 near Olonkinbyen, Norway on 05 October at 10 km; M4.6 near Olonkinbyen, Norway on 05 October at 10 km.
That is 64% above the 2 events Norway averages per month across the 12 months on record.
