Table 1 The registered earthquakes during the measuring period with a magnitude higher than 2.0 are listed below with the corresponding geographical coordinates (Lat / Long), magnitude (M) and depth of the earthquakes. E1, E2, E3, E4 are identification numbers for the earthquakes which are mapped in Figs. 4, 5 and 6. The distances between the epicentres and the measurement locations Baden (B) and Rheinfelden (R) were calculated. The strain radius was calculated by means of Eq. 1. Strains at the monitoring site R and B are calculated by Eq. 2
