Electrical conductivity data of S13 borehole from 140 days before the Amatrice earthquake (24 August 2016 (doy 237) at 01:36:32 UT). The anomaly starts about 60 days before the mainshock in accordance with weak deviation from zero of Kurtosis of hydraulic pressure data in Fig. 13 (blue line); in the period from May 2015 to May 2016 we did not observe any significant variation. (b) Electrical conductivity data of Amatrice earthquake of 24 August 2016 (01:36:32 UT) from 00:00 to 03:00 UT.
