DETECTION OF RADON EMISSIONS DURING 2016/2017 EARTHQUAKES IN ABRUZZO (ITALY)

«Aracne» is an Italian monitoring network, part of the «Tellus» project, for the real-time detection of radon emissions from Earth’s subsoil. The Aracne network was launched in August 2015, with the first multi-parameter station in Pizzoli, in central Italy, followed in December 2016 by the one of Cagnano Amiterno and finally the station of Capitignano, which will be installed by early 2018. The stations provide data at 10-minute intervals, together with all meteorological values outside the station and at the exact measuring point, such as humidity and temperature measured at about 20 cm from the radonometer that is being used. The stations are identical both for instrumentation and for measuring place characteristics, designed in such a way to maintain constant temperature and humidity. This project makes the stations of the Aracne network unique in the world as far as detection methodology is concerned. The Pizzoli station provided very interesting data during the seismic crisis that hit central Italy on 24 August 2016, 30 October 2016 and 18 January 2017 with three earthquakes of Mw 6.0, Mw 6.5, Mw 5.5 respectively.
