The verdict
Norway is below the global median in catalogued seismic activity, with 20 M4+ earthquakes logged since 2005 and 0 major M6+ events since 1900, the strongest reaching magnitude 5.2.
- N/A
- no yearly breakdown available
- N/A
- average recorded event depth
- 0%
- of events are shallow (<70 km, the most damaging kind)
Average catalogued magnitude is 4.4 - most events are moderate M4-5 tremors that are felt but rarely cause damage. On the M4+ activity ladder Mauritania sits immediately above at 21 events and Grenada sits immediately below at 19.
Where Norway sits in the catalog
Rank 120th of 187 tracked countries (35th percentile by M4+ count since 2005). On the M4+ activity ladder Mauritania sits immediately above at 21 events and Grenada sits immediately below at 19.
- Mauritania - next more active (21 M4+)
- Grenada - next less active (19 M4+)
Same M4+ count, broken by peak magnitude
2 tracked countries share Norway's exact count of 20 M4+ events since 2005. Among that cohort, Norway ranks 2nd of 2 by strongest recorded magnitude (M5.2).
| Country | M4+ count | Strongest |
|---|---|---|
| Namibia | 20 | M5.4 |
| Norway (this page) | 20 | M5.2 |
0 of 20 catalogued M4+ events since 2005 reached M6.0 or higher.

What Norway's numbers mean
Norway ranks 120th of 187 countries tracked - a country with limited but non-zero seismic activity.
- About 1 M4+ earthquakes strike Norway per year on average. See the full country ranking
- 0% of Norway's catalogued major earthquakes are shallow (under 70km) - shallow events generally produce stronger surface shaking than deep ones of the same magnitude. How depth affects shaking
- The strongest catalogued event reached M5.2. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
