GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 3.1 GNGTS 2023 The proposed methods are applied to data collected from seismic monitoring stations of the Alpine Geothermal Power Production (AGEPP) geothermal project ( https://www.agepp.ch/ ) , in Vaud, Switzerland. The network has been deployed to evaluate the natural and induced seismicity during the activities on-site. The effect of the number of stations, inter-station distances, noise directionality and recording time are analysed.
