Radon-in-soil variations related to volcanic activity

Soil radon flux and concentrations in hydrothermal area of the Tatun Volcano Group, Northern Taiwan

“…concentration variations in volcanic areas has been considered as a useful tool to investigate the volcanic activity in one area (Seidel et al, 1988;Segovia et al, 1997Segovia et al, , 1999Segovia et al, , 2001Segovia et al, , 2003Immè et al, 2006a, b;Neri et al, 2006Neri et al, , 2007Cigolini et al, 2009;Moreno et al, 2009;Viveiros et al, 2009).…”

Report on Correlation between Radon Outgassing and Aftershocks Activity along the Bam Fault in Kerman Province of Iran

“…A number of authors [1][2][3][4][5][6][7][8] make this kind of predictions on the basis of soil-gas information, mainly the radioactive radon gas ( 222 Rn) data. Thus, an enhanced seismic activity responsible for changes in the convective velocity may account for anomalous temporal variations of the radon concentration and that of other gas species in the subsurface soil air [7][8][9].…”

Soil radon concentration and volcanic activity of Mt. Etna before and after the 2002 eruption

“…Other studies have been performed in volcanic areas (Monnin and Seidel, 1991;Heiligmann et al, 1997;Zimmer and Erzinger, 2003;Segovia et al, 1997Segovia et al, , 1999Connor et al, 1996;Gasparini and Mantovani, 1978). Among them, Gasparini and Mantovani (1978) reported one of the first best-documented cases of 222 Rn variations clearly related to the volcanic activity at the Karymsky volcano in Kamchatka.…”

“…Various radon investigations have also been conducted at the Popocateptl volcano in Mexico (Segovia et al, 1997(Segovia et al, , 1999. The radon concentration showed a trend compatible with the evolution of the volcanic activity.…”
