Effect of the parameters involved in the Detection Algorithm on the issued alarms preceding a given earthquake. (a,b) refer to radon time series of the stations NRCA and CTTR, respectively, and to the Mw 6.5 EQ3. Red/blue circles indicate if the alarm before that earthquake is issued/not issued. The combination of parameters durmedmob/pardaily (p1/p2) selected is highlighted in yellow. (c) refers to station CTTR and to the alarm preceding the Mw 6 EQ1. (d,e) Number of false alarms delivered running the algorithm on radon data from stations NRCA and CTTR, respectively, with the input parameters selected above. (f) dependence of false alarms on the input parameter pardaily (p2).
