RADIO SIGNALS AND CHANGES OF FLOW OF RADON GAS (RN222) WHICH LED THE SEISMIC SEQUENCE AND THE EARTHQUAKE OF MAGNITUDE MW 4.4 THAT HAS BEEN RECORDED IN CENTRAL ITALY (BALSORANO, L'AQUILA) ON NOVEMBER 7, 2019.

Through this work the authors want to ascertain the possible relationship have theorized that between the pre-seismic increase of Radon gas (Rn222) and the production of radio-pre-seismic anomalies in the Apennines Central Italy: phenomena that have a substrate common, namely the creation of fractures and micro-fractures of the crust due to tectonic stress. The radio-pre-seismic anomalies (Electromagnetic Seismic Precursors or ESPs) are of natural radio emissions generated through the deformation and rupture (microfractures and fractures) of the crystalline lattices present in the rocks that make up the earth's crust. The Rn222 gas is, instead, is the only gaseous element produced by dell'Uranio238 decay which is able to filter from the mantle to the ground through the earth's crust in thermodynamic function of the energy produced in the mantle and in relation to the permeability (fractures and geological characteristics) of the earth's crust. Central Italy is dotted with numerous faults and micro-faults capable of generating destructive earthquakes. Under this scenario, it is convenient to install a network of multi-parametric monitoring in Central Italy for the study of socalled "Electromagnetic Seismic Precursors" (ESPs) and "Chemical Seismic Precursors" (CSPs), in our case, identifiable by variations Rn222 of the gas flow. This paper will present the correlation data on electromagnetic anomalies (ESPs) and chemical (Rn222) that have been observed to precede the seismic sequence and the Mw 4.4 earthquake that was recorded in Balsorano (AQ) November 7, 2019 at 17:35:21 UTC (Fig. 1).
