Volcanic plume fingerprint in the groundwater of a persistently degassing basaltic volcano: Mt. Etna
Abstract The chemical composition of the groundwater at Mt. Etna was investigated in order to determine the extent to which the persistent plume affects the chemical composition of circulating waters. Samples from 31 springs and wells were collected during June and July 2014 and analyzed for their c...
