Characterization of the detection sensitivity level of the April event. Panel (a): Characteristic functions of the recursive STA/LTA algorithm, which was applied to each strain-rate time-series. Red and blue dots show the coordinates at which the trigger turns on and off, respectively, with the parameters in Tabel 1. Panel (b) Evolution with depth of the maximum STA/LTA ratio measured along the characteristic functions presented in panel (a)
