Soil gas radon measurements were performed continuously in the east flank of Mt. Etna volcano in order to correlate soil gas radon anomalies with geodynamic processes. Both volcanic activity and seismic monitoring have been carried out by means of seismic stations and cameras located around the volcano, while the evaluation of radon data has been done by using basic statistic and signal processing methods. The first analysis seems to indicate a clear correlation between soil gas radon variations and volcanic activity of Mt. Etna, being the November 2015 eruption preceded by a sharp decrease of radon levels in both stations.
