Seismicity within the Hegau-Bodensee graben in 2015/16. a Overview map with SED-routine hypocenter locations (blue circles: events in 2015; red circles: events in 2016) and mapped normal faults (after Egli et al. 2016). See box in Fig. 2 for location of the overview map. Nf: Neuhausen fault, Hg: Hegau graben; Rf: Randen fault; Sf: Schienerberg fault. b Map view of relative relocations of the Basadingen-Schlattingen (TG) sequence between September 2014 and May 2016 using double-difference techniques in combination with waveform cross-correlation. c Depth cross-section of the relocated Basadingen-Schlattingen sequence along a SW-NE striking profile AA’. Colors indicate origin time of the events. The focal mechanism of the ML 2.2 event of May 31st is shown as lower hemisphere projection in map view and projected onto the depth profile in the cross-section. Relative relocations in combination with the focal mechanism suggest a NE dipping normal fault in the crystalline basement
