  1. Cluster, main clusters on the FL; date, date of reference event; time, UTC time of reference event; lat/lon, latitude and longitude of reference event; X/Y/Z, hypocenter location by HypoLine software (Joswig 2008; Vouillamoz et al. 2016) in the CH1903-LV03 projection system; ML, local magnitude (Vouillamoz et al. 2016); STAF tS–tP, S–P travel-time differences of reference event picked at station STAF; rel. tS–tP, maximum relative S–P travel-time difference observed between the reference event and the clustered events; FM, focal mechanism [solutions published in Deichmann et al. (2010) for event (1) and (2) and in (Vouillamoz 2015) for event (4)]
