Fault-plane solutions based on first-motion polarities for three events in 2013 (upper row St. Gallen, Baltzers ML 4.1 mainshock, and Baltzers ML 3.7 aftershock; see Table 3). Symbols and explanation as in Fig. 5. For two of these events (lower row), the double-couple part of the full waveform moment tensor solution is shown as a beach-ball symbol (St. Gallen, Baltzers mainshock—items marked MT in Table 3). Black bold lines indicate the preferred first-motion solution of the same event
