Continuous radon monitoring during seven years of volcanic unrest at Campi Flegrei caldera (Italy)

摘要

Map of the Campi Flegrei caldera (Naples-Italy). The map, modified after (10.1016/j.apradiso.2020.109140) using the PAINT (Microsoft Corporation, Version: 6.1907.18017.0), shows the structural setting of the caldera characterised by tectonics and volcano-tectonic activity. The two radon monitoring sites of Monte Olibano and Monte Sant’Angelo, and the others monitoring sites of geochemical and geophysical parameters are reported. The squares represent the Campi Flegrei seismic network in green and the NeVoCGPS network in orange (see Methods).
