Radioactivity of Mt. Etna volcano and radionuclides transfer to groundwater [PDF]

Annals of Geophysics, 2019
The paper presents the results of a radiometric survey carried out on the eastern flank 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 ...

Analytical and 3-D numerical modelling of Mt. Etna (Italy) volcano inflation [PDF]

Geophysical Journal International, 2005
Since 1993, geodetic data obtained by different techniques (GPS, EDM, SAR, levelling) have detected a consistent inflation of the Mt. Etna volcano. The inflation, culminating with the 1998– 2001 strong explosive activity from summit craters and recent ...

Experimentation of new technologies for volcano gravimetry at Mt. Etna

, 2023
Among the geophysical techniques used to monitor volcanic unrest, only gravimetry can supply direct information on changes in the distribution of underground mass over time and can thus provide unique insight into processes such as magma accumulation in ...

Mud volcano fields around Mt. Etna

, 2009
We have studied four mud volcano fields located in eastern Sicily, around the Mt. Etna edifice. Three of them are located on the southern flank of Etna, between the Paternò and Belpasso villages and, based of their location, are named “Salinelle dei ...

Crustal stress pattern at Mt. Etna volcano

Journal of Geodynamics
Stress fields may exhibit variegated patterns, especially in volcanic areas where several processes superimpose their effects in space and time. The comprehension of such patterns may not be straightforward to investigate.

Basement sliding and the formation of fault systems on Mt. Etna volcano [PDF]

Journal of Volcanology and Geothermal Research, 2022
The influence of faulting on the eruptive mechanisms of Mt. Etna has been intensively studied, especially regarding the importance of regional tectonics, magma pressure, gravitational spreading and east flank instability. Here we examine the influence of an additional process: the wholesale sliding of the Etna massif along its sloping basement (Murray ...

The cryptic summit graben of Mt. Etna volcano [PDF]

Journal of Volcanology and Geothermal Research, 2019
Previous studies have inferred the likelihood of a summit graben at Mt. Etna, but until now there has been no direct observation or evidence of such a feature. Here, the results of 43 years of deformation measurements at the summit are reported, in which the presence of an actively forming north-south graben 1.5 km wide is evident, with a maximum ...

Laboratory simulations of fluid/gas induced micro-earthquakes:application to volcano seismology [PDF]

, 2014
Understanding different seismic signals recorded in active volcanic regions allows geoscientists to derive insight into the processes that generate them.

Infrasonic evidences for branched conduit dynamics at Mt. Etna volcano, Italy [PDF]

Geophysical Research Letters, 2009
On multi‐vents volcanoes changes in activity between different vents reflect a complex fluid‐dynamics of the shallow feeding systems and are often explained numerically and experimentally in terms of conduit branches and bifurcations. We present new geophysical constraints on the shallow feeding system of Etna volcano derived from array analysis of ...

Twelve Years of Ground Deformation Studies on Mt. Etna Volcano Based on GPS Surveys

, 2004
GPS (Global Positioning System) monitoring has been performed on Etna volcano since 1988, making this volcano one of those with the longest records of GPS data.
