Time-series analysis of radon monitoring in soil gas in association with earthquakes in Stivos faulting, at Lagadas basin, North Greece

Abstract

Time series analysis was applied to the continuous radon level, temperature, pressure, and rainfall to find clear earthquake signals. Radon signals appeared a few days after heavy rains, and radon signals associated with events M = 3.8–4.2 were detected 12 up to 36 days before. The events are complete data recorded from 1983 to 1986, giving discussion and conclusion on M with prediction time and radon anomaly detected in the Stivos faulting near Thessaloniki, N. Greece.
