Plastino Ciencias de la Tierra Radon earthquake radon and hydrogeochemical anomalies From May 1996, measurements of the radon content in groundwater and other parameters (pH, electrical conductivity,pressure of dissolved gases and groundwater temperature) were conducted at the Gran Sasso underground laboratory of theNational Institute for Nuclear Physics, Italy, using multiparametric equipment. We have analyzed the correlations between radonvariations and the stress-strain processes in the rock, and the radon diffusion processes related to groundwater geochemistry. Timeseries analysis showed strong anomalies in pH, radon concentrations and pressure of dissolved gases, which highly correlate withthe Umbria-Marche seismic sequence of 1997-1998. This may be caused by a transient compression phase producing a change ofcarbon dioxide content in groundwater. Spike-like anomalies of electrical conductivity correlate with local seismic events thussuggesting variations in groundwater dynamics. 2002 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56841403 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.41 |
