Earthquakes in Norway — March 2025

5 earthquakes were recorded in Norway during March 2025, an average of 0.2 per day.

5 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 6.5 earthquake near Olonkinbyen, Norway on 10 March 2025 at 02:33 UTC. A magnitude 6.5 earthquake radiates roughly 84,802 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 4 in the magnitude 4 range, 1 in the magnitude 6 range.

Activity peaked on 10 March, when 2 events were recorded.

1 event(s) this month carry a USGS link to NOAA tsunami information; the flag does not indicate whether a tsunami occurred.

The month's largest events were M6.5 near Olonkinbyen, Norway on 10 March at 10 km; M4.6 near Olonkinbyen, Norway on 10 March at 10 km; M4.5 near Olonkinbyen, Norway on 04 March at 10 km.

That is 173% above the 2 events Norway averages per month across the 12 months on record.

This month also holds the strongest earthquake recorded in Norway in our entire catalogue.
