With a magnitude of 4.3, the strongest earthquake occurred on October 25 near Elm, in the Glarus region, said Monday the Swiss Seismological Service at the Polytechnic School of Zurich (ETHZ). It was partly felt as far as Ticino and Lake Constance and was followed by more than 250 aftershocks, some of which reached a magnitude of 3.9 on the Richter scale.

An earthquake with a magnitude of 3.1 had already occurred in the same fault system on May 26. It had been followed by dozens of aftershocks.

In total, the Glarus seismic sequence has caused more than 350 earthquakes and “contributes significantly to the number of earthquakes above the average observed in 2020”, according to the press release. No significant damage was recorded.

The influence of the coronavirus

In addition to seismic waves, stations in Switzerland also measure “background noise”, originating from natural vibrations caused by wind or waves, for example, but also by human activities, such as automobile traffic or construction.

The semi-containment of the spring resulted in “a significant reduction in this background noise”, notes the Swiss Seismological Service.

This period of calm is the longest on record. In mid-June, the noise increased again.

In Switzerland, the last strong earthquake – with a magnitude of 5.8 – took place in Valais on January 25, 1946. It left four victims, many injured and 3,500 buildings damaged.
