All epicentres and selected focal mechanisms of earthquakes recorded by the Swiss Seismological Service: a during 2017; b during 2018. Events and focal mechanisms (lower hemisphere projections) discussed in the text are Göschenen (GOE), Urnerboden (URB), Vallorcine (VAL), Grenchen (GRE), Daillon (DAI), St. Silvester (STS), Château-d'Oex (CDO), Zug (ZUG), Anzère (ANZ), Klostertal (KLT), Herrischried (HER), Rhinegraben (RIG), Châtel-St-Denis (CSD), Dent de Morcles (DDM), Martigny (MAR), Fribourg/Tafers (FRI), and Sion (SIO). Additional events with focal mechanisms are listed in Additional file 1: Table S4. Colour of focal mechanism indicates focal depth. Background colours outline major tectonic units after Swisstopo (2005). Grey solid and dashed lines indicate faults and fault systems.
