Earthquakes in Norway — September 2025
1 earthquakes were recorded in Norway during September 2025, an average of 0.0 per day.
1 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 10 km.
The month's largest event in Norway was a magnitude 4.7 earthquake near Longyearbyen, Norway on 15 September 2025 at 14:21 UTC. A magnitude 4.7 earthquake radiates roughly 169 tons of TNT equivalent in seismic energy.
That is below the Norway monthly average of 2 events over the period we cover — a comparatively quiet 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 1 in the magnitude 4 range.
That is 45% below the 2 events Norway averages per month across the 12 months on record.
