“…In a recent paper (Cigolini et al, 2009), we showed that tidal forces actively modulate radon degassing at Stromboli volcano, supporting the earlier findings of Barnet et al (1997). Therefore, in analyzing our data we considered the normalized sinusoidal signal constructed from the values of Rn soil concentrations and, consequently, can be used in filtering the radon signal.…”

We present the results of one year of continuous radon monitoring at Stromboli volcano collected at two automated real-time stations. These were deployed on the NE flank (at 520 m a.s.l.) and within the summit area (900 m a.s.l. an increases in radon concentrations were observed during periods of higher rainfall conditions. Therefore, trends in radon concentrations may be decoupled from those of other geochemical parameters (CO 2 fluxes and CO 2 /SO 2 plume ratios) during periods of heavy to moderate rainfalls.Multiple Linear Regression statistics (including the effects of soil temperature, atmospheric pressure and tidal forces) led us to compute the residuals given by the difference of measured and calculated 222 Rn concentrations. The cross-check between the daily measured radon activities and the absolute variations in radon residuals, for the data collected at the summit station, give us the opportunity to suggest a methodological approach that can be used in the attempt of predicting some major changes in volcanic activity.

“…In this sense, the significance of the 12h-barometric tides in the 222 Rn signal within subterranean environments has been previously documented. Some studies reveal a high sensitivity of radon exhalation flux from the soil and host rock to changes of atmospheric pressure (Richon et al, 2009) or due to increases of groundwater level which displaces the gas into the subterranean atmosphere (Barnet et al, 1997), being both processes caused by earth tides.…”

“…However, other studies (Aumento, 2002;Groves-Kirkby et al, 2006;Crockett et al, 2006a) indicate that a consistent meteorological influence cannot be identified as giving rise to variability in radon time series, and suggest gravitational tides as a influencing factor on radon variability, since both earth tides and ocean tidal loading may drive periodic radon exhalation via crustal extension/ compression and geophysically driven groundwater level variations (Barnet et al, 1997;Hartmann, 2005). In addition to anthropogenic, climatic and tidal effects as possible influences, indoor radon levels were also reported to be affected by seismic events (Crockett et al, 2006b).…”
