A large temporal anomaly was retrieved in the total geomagnetic field series recorded in 1981 on Mt. Etna at two continuously recording magnetometers, and associated with the March 17-23 eruption of the volcano. Variations were of such large scale that a ... see more

The paper presents the results of a radiometric survey carried out on the eastern ank of Mt. Etna over an area of approximately 120 km2. Activity concentrations of 238,234U, 232,230,228Th, 226,228Ra, from 238U and 232Th decay chains, and potassium 40K wer... see more

The paper presents the results of a radiological survey carried out on the eastern flank of Mt. Etna over an area of approximately 120 km2. Activity concentrations of uranium isotopes 238,234U, thorium isotopes 232,230,228Th, two radium isotopes 226,228Ra... 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

In the present paper we describe the on-land field operations integrated in the TOMO-ETNA experiment carried out in June-November 2014 at Mt. Etna volcano and surrounding areas. This terrestrial campaign consists in the deployment of 90 short-period porta... see more

The TOMO-ETNA experiment was devised to image of the crust underlying the volcanic edifice and, possibly, its plumbing system by using passive and active refraction/reflection seismic methods. This experiment included activities both on-land and offshore ... see more

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
