Earthquakes in Norway

Norway appears infrequently in the record, with just 2 events in the past 30 days, of which 21 reached magnitude 4 or above, the point at which shaking becomes widely noticeable. Activity here is almost entirely crustal, which means shaking at the surface is strong relative to the magnitudes involved.

22 earthquakes have been recorded in Norway in our catalogue, 2 of them in the past 30 days.

The average magnitude is 4.5 and the average focal depth 10 km. 21 events reached magnitude 4 or above and 2 reached magnitude 5 or above.

The strongest earthquake recorded in Norway in this period was a magnitude 6.5 event near Olonkinbyen, Norway on 10 March 2025, at a depth of 10 km. A magnitude 6.5 earthquake radiates roughly 84,802 tons of TNT equivalent in seismic energy.

Locations recording the most events include Olonkinbyen (14), Longyearbyen (5), Sørumsand (1), Måløy (1), Ørnes (1).

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 3 range, 19 in the magnitude 4 range, 1 in the magnitude 5 range, 1 in the magnitude 6 range.

The busiest single day was 05 October 2025, with 3 recorded events.

1 of these events carry a USGS link to NOAA tsunami information. That link flag does not mean a tsunami occurred or that a warning was issued.
