Diagram of the monitored Fluorescence intensity of the thermal water in Rheinfelden (R) over the measuring period. The fluorescence intensity at wavelength 470 nm is presented in the blueish curve whereas the greyish curve presents the fluorescence intensity at 525 nm. The orange squares depict the registered earthquakes with the location and the magnitude in brackets. The earthquake close to Albstadt (E3) does not appear on the figure because of the distance between the measurement location and the epicenter, which exceeded 100 km. The earthquakes are scaled depending on their precursor manifestation zone, which was calculated by Eq. 1. The blackish – dashed line marks the interruption of the measurement because of the loss of power supply
