Seismograph stations in Switzerland and surrounding regions with on-line data acquisition operational at the end of 2016. Stations of the “Switzerland Seismological Network” (network code “CH”) are indicated with labels. The stations defined as high-gain (HG) are mostly equipped with broad-band or 5-s sensors, whereas the strong-motion stations (SM) are accelerometers (see also Table S-1–S-3 in the Electronic Supplement). Yellow triangles mark complementary permanent or temporary stations with real-time data acquisition, used to improve detection and location of seismicity. Colors projected onto the topographic relief in the background show the lateral variation of the magnitude of completeness (MC) for on-line stations operating at the end of 2016, assuming a detection probability of 0.99, a minimum number of 6 automatic triggers, and a hypothetical focal depth of 5 km. Bold, white lines indicate MC contours of 1.0, 1.5 and 2.0
