On September 10, a magnitude 4.7 earthquake struck near Sierentz in neighboring France — the fifth strongest in the region since records began in 1975. In Switzerland, around 11,000 people reported the earthquake, a new record.

The second strongest earthquake of the year with a magnitude of 3.9 occurred near Triesenberg in Liechtenstein. It was felt as far as St. Gallen, 50 km away.
However, no damage was found in Switzerland last year. A minor disturbance was last recorded in 1991 after an earthquake of magnitude 5.0 in Vaz in the canton of Graubünden.
Further back, more violent earthquakes are not uncommon: in 1356, an earthquake with a magnitude of 6.6 destroyed the city of Basel.
The strongest earthquakes since the introduction of modern measuring methods in the region were recorded in Annecy, France, in 1996 and Bormio, southern Switzerland, in 1999, each with a magnitude of 5.1.
Overall, the 900 recorded in 2022 marked a slightly lower total than in previous years. The number of tremors with a magnitude of over 2.5 on the Richter scale – and thus noticeable for people – was 28, slightly above average.
