Attenuation and Source Parameters of Shallow Microearthquakes at Mt. Etna Volcano, Italy

Bulletin of the Seismological Society of America, 2007
We estimated the attenuation laws of high-frequency seismic waves in the shallow crust (depth 5 km) and earthquake source parameters by using a se- lected data set of 320 shallow events (2.6 MD 4.2), recorded at Mt. Etna volcano during the last two flank eruptions occurring in 2001 and 2002-2003.

High precision tilt observation at Mt. Etna Volcano, Italy

Acta Geophysica, 2011
In 2007–2008, we installed on Mt. Etna two deep tilt stations using high resolution, self-leveling instruments. These installations are a result of accurate instrument tests, site selection, drilling and sensor positioning that has allowed detecting variations related to the principal diurnal and semidiurnal tides for first time on Mt.

The detectability of infrasound in The Netherlands from the Italian volcano Mt. Etna

Journal of Atmospheric and Solar-Terrestrial Physics, 2005
Abstract Infrasound from the eruptions of Mt. Etna was detected in The Netherlands at the Deelen Infrasound Array (DIA) during the summer of 2001. Zonal cross winds lead to a deviation in the observed back azimuth. An average azimuthal deviation of 2 .

Earlier alkaline and transitional magmatic pulsation of Mt Etna volcano

Earth and Planetary Science Letters, 1998
The observation of glass inclusions with alkalic and transitional compositions in single olivine crystals from Aci Castello hyaloclastites indicates that small volumes of alkalic melts preceded tholeiite eruptions during the onset of Mt Etna volcanism.

Modelling the long‐term deformation of the sedimentary substrate of Mt. Etna volcano (Italy)

Terra Nova, 2015
AbstractThis study investigates in detail the deformation events that have affected the sedimentary successions forming the substrate of Mt. Etna volcano (Italy). Based on the geometric reconstruction of a buried sedimentary marker, we have been able to identify and quantify the effects of three different mechanisms of deformation that have affected ...

Mud volcano fields in the Mt. Etna area (eastern Sicily)

2009
In this paper we describe briefly the activity and evolution of four mud volcano fields located in eastern Sicily, around the Mt. Etna edifice. Three of them, called “Salinelle dei Cappuccini”, “Salinelle del Fiume” and “Salinelle del Vallone Salato” based on their location, occur on the southewestern flank of Etna, between the Paternò and Belpasso ...

Multidisciplinary study of the Trecastagni fault (Mt. Etna volcano, Sicily)

2020
<p>The complex interaction between regional stress, gravity forces and dike-induced rifting of Mount Etna, seems to have a role in the eastward movement of the Mt. Etna eastern flank. In this context, the Trecastagni-Tremestieri Fault system identifies the southern boundary of the unstable sector.</p><p& ...

Assessment and Modeling of Lava Flow Hazard on Mt. Etna Volcano

2011
A methodology for constructing a probability map of lava inundation by considering the past eruptive behavior of the Mt Etna volcano is described. The basic a priori assumption is that new vents will not form far from existing ones and that such a distribution can be performed using a Gaussian kernel.

Basaltic volcanoes as large-scale aerators: the example of Mt. Etna

2008
The recognition and simulation of the patterns of gas release from active volcanoes in relation to those of magma supply and transfer are a major geochemical goal. At basaltic volcanoes such as Mt. Etna (Sicily, Italy) this knowledge would greatly assist our comprehension of the mechanisms of magma rise and injection at different storage levels, from ...
