First characterisation of minor and neglected Vitis vinifera L. cultivars from Mount Etna
Sicily grapevine biometric SSR identification
2018/3/6
Eight minor and neglected cultivars of Vitis vinifera L. were characterised according to their ampelographic and agronomic
traits and discriminated by molecular analysis with SSR markers. These resul...
The geodynamics of Mt. Etna volcano during and after the 1984 eruption
Mt. Etna earthquakes focal mechanisms stress field eruption
2015/10/8
Data concerning M > 2.5 earthquakes that occurred at Mt. Etna volcano (Sicily, Italy) during the period April 15th - October 29th, 1984 are here presented and discussed. Only those events with reliabl...
Maximum entropy estimation of values at Mt. Etna: comparison with conventional least squares and maximum likelihood results and correlation with volcanic activity
frequency-magnitude distribution maximim entropy method Mt. Etna
2015/10/8
The variations of the b coefficient in the frequency-magnitude relationship for earthquakes which occurred at Mt. Etna from 01/01/90 to 31/12/92 are analyzed; the completeness threshold for our earthq...

Magnetotellurics Mt. Etna Volcanic structure feeding system
2015/9/28
he results of a magnetotelluric (MT) survey performed at Mt. Etna (Sicily, Italy) are presented and discussed.
The MT interpretation is preceded by the description of the data managing strategy used ...
Temperature distribution analysis of July 2001 Mt. Etna eruption observed by the airborne hyperspectral sensor MIVIS
remote-sensing volcano monitoring thermal infrared dual-band technique
2015/9/17
On 17th and 18th July 2001, several fractures opened on Mt. Etna southern flank generating different lava flows
spreading both in Valle del Bove and towards Nicolosi. On 29th July the image spectrome...
Aerosol optical thickness of Mt. Etna volcanic plume retrieved by means of the Airborne Multispectral Imaging Spectrometer (MIVIS)
aerosol optical thickness volcanic plume MIVIS DEM radiative transfer model 6S inversion technique
2015/9/16
Within the framework of the European MVRRS project (Mitigation of Volcanic Risk by Remote Sensing
Techniques), in June 1997 an airborne campaign was organised on Mt. Etna to study different character...
Finite element analysis of ground deformation due to dike intrusion with applications to Mt. Etna volcano
FEM ground deformation dike intrusion real medium
2015/9/15
A 2D finite elements study was carried out to analyse the effects caused by dike intrusion inside a heterogeneous medium and with a realistic topography of Mt. Etna volcano. Firstly, the method (dimen...
The relationship between volatile content and the eruptive style of basaltic magma: the Etna case
volatile content eruptive style
2015/9/14
Fourier Transform Infrared (FT-IR) spectroscopic analyses of melt inclusions from four explosive eruptions of Etna (Italy) were conducted to determine pre-eruptive dissolved volatile concentrations. T...
Gas radon emission related to geodynamic activity on Mt. Etna
radon geodynamical precursor Mt. Etna
2015/9/10
We report preliminary observations on possible correlations between anomalies of subsoil radon concentration
and geodynamical events on Mt. Etna. In recent years several studies have been carried out...
In order to verify the duration magnitude MD we calculated local magnitude ML values of 288 earthquakes occurring
from October 2002 to April 2003 at Mt. Etna. The analysis was computed at three digit...
Intrinsic Qp at Mt. Etna from the inversion of rise times of 2002 microearthquake sequence
intrinsic quality factor stress drop rise time corrected Akaike information criterion
2015/9/8
About three-hundred microearthquakes, preceeding and accompanying the 2002-2003 Mt. Etna flank eruption,
were considered in this study. On the high-quality velocity seismograms, measurements of the f...
Kinematics and strain analyses of the eastern segment of the Pernicana Fault (Mt.Etna,Italy) derived from geodetic techniques (1997-2005)
GPS EDM ground deformation Pernicana Fault Mt. Etna
2015/9/8
This paper analyses the ground deformations occurring on the eastern part of the Pernicana Fault from 1997 to 2005. This segment of the fault was monitored with three local networks based on GPS and E...
