From the Swiss Seismological Service (SED) at ETHZürich:

Starting in the night of 4 to 5 November, 2019, an exceptionally active earthquake swarm is ongoing near Savièse, north of Sion VS. Until the morning of 6 November, the seismic network of the Swiss Seismological Service at ETH Zurich (SED) has recorded more than 100 events. Twelve of these had magnitudes of 2.5 or larger and were widely felt by the population of the Sion region up to Sièrre. The four strongest quakes reached magnitudes between 3.0 and 3.3 and were sporadically felt even in the Bernese Oberland. Overall, the SED has collected several hundred felt reports on its website.
Such an accumulation of earthquakes is rather untypical for Switzerland. Earthquake swarms with many events within days or weeks happen regularly. However only rarely as many perceptible earthquakes occur within a small period of time. Still, predicting the future development of this sequence is not possible. Typically, the seismic activity decays after days, at most after weeks. However, there is a probability of 5 to 10 percent for significantly stronger earthquakes to occur within the next days....MORE
