a Fribourg high-quality events (epicentral uncertainty <2 km) highlight two zones of apparent clustered seismicity: the Fribourg Lineament (FL) and the Fribourg Cluster (FC) below the city of Fribourg. b, c N–S (E 583′000) and W–E (N 182′000) hypocenter projections. Base Tertiary and Base Mesozoic horizon are interpolated from seismic imaging surveys (Interoil 2010). Resolved focal depths are restricted to the sedimentary cover (Vouillamoz et al. 2016)
