Monitoring of hydrothermal fluid emissions can provide detailed information about convective upwelling of geothermal fluids and their geochemical characteristics, as a function of tectonic stress or deeper gas input. In particular, at the Salinelle of Mt.... see more

We monitored the soil gas emission of CO2 from selected sites of Mt. Etna volcano during the period February 2009 to December 2010 by measuring periodically the soil CO2 efflux together with the associated stable carbon isotope composition of CO2 from Feb... see more

Instrumental seismic catalogues are an essential tool for the zonation of the territory and the production of seismic hazard maps. They are also a valuable instrument for detailed seismological studies regarding active volcanoes and, above all, for interp... see more

This work focuses on the evaluation of Aerosol Optical Thickness (AOT) in Mt. Etna volcano area starting fromthe analysis of MIVIS VIS images. MIVIS images and ancillary data (atmospheric profiles, photometric measurements,atmospheric infrared radiances, ... see more

This paper analyses twelve etnean earthquakes which occurred at various depths and recorded at least by eleven stations. The seismic stations span a wide part of the volcanic edifice; therefore each set of direct P-wave arrival times at these stations can... see more

Fault-plane solutions of some tens of local earthquakes which occurred at Mt. Etna volcano during 1983-1986 have been inverted for stress tensor parameters by the algorithm of Gephart and Forsyth (1984). Three seismic sequences were focused on which respe... see more

A ground magnetic study was performed on the northern upper flank of Mt. Etna to provide new insights into subsurface volcano-tectonic structures. The high resolution magnetic survey was focused on the main structures of Piano delle Concazze, a large flat... see more

Volcanoes and fault zones are areas of increased heterogeneity in the Earth crust that leads to strong scattering of seismic waves. For the understanding of the volcanic structure and the role of attenuation and scattering processes it is important to inv... see more
