a Distribution and magnitudes of earthquakes recorded in northeastern Switzerland according to ECOS-09 (Fäh et al. 2011). This catalogue comprises seismic events between the year 1065 and June 2009. SHmax and Shmin orientations are after Heidbach and Reinecker (2013). b Zoom of the same dataset as in a, but with the induced 2013 sequence in orange and all available fault plane solutions of the area. Note the natural ML 2.1 event of 2012 close to the RFZ. The (superposed) orange circles represent preliminary relative relocations of the sequence induced at borehole SG GT-1 in 2013 according to Diehl et al. (2014b). The fault plane solution of the ML 3.5 event is according to Diehl et al. (2014a), the two ML 2.1 events are according to Diehl et al. (2014b), the ML 3.2 event is according to Deichmann (1990) and the ones in Lake Constance are according to Pavoni (1980)
