Cumulative number of events and magnitude of the induced earthquakes in St. Gallen as detected by STA/LTA trigger algorithms using on-line stations of the St. Gallen network (Fig. 2) complemented by stations of the national high-gain network in the region. The routinely derived network ML is overestimated in cases where magnitudes are determined from local SGT stations alone
