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...
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...
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...
Tidal gravity observations at Mt. Etna and Stromboli: results concerning the modeled and observed tidal factors
Tidal gravity models Tidal loading
2015/9/1
Continuous gravity observations performed in the last few years, both at Mt. Etna and Stromboli, have prompted
the need to improve the tidal analysis in order to acquire the best corrected data for t...
Surface roughness of pyroclastic deposits at Mt. Etna by 3D laser scanning
surface roughness pyroclastic deposits Laser 3D
2015/9/1
The terrestrial 3D Laser Scanning technique has been applied to analyse the surface roughness of pyroclastic deposits on volcanic surfaces at Mt. Etna. This technique allowed the construction of high ...
Shear-wave velocity structure at Mt. Etna from inversion of Rayleigh-wave dispersion patterns (2 s < T < 20 s)
Mount Etna Rayleigh-wave dispersion S-wave velocity modeL Non-linear inversion Triangle method
2015/8/28
In the present study, we investigated the dispersion characteristics of medium-to-long period Rayleigh waves (2 s < T < 20 s) using both single-station techniques (multiple-filter analysis, and phase-...
Displacement across the Trecastagni Fault (Mt. Etna) and induced seismicity: the October 2009 to January 2010 episode
Wire extensometer creep shallow earthquakes fault dynamic
2015/8/27
The Trecastagni Fault (TF) is a NNW-SSE tectonic structure inside Mt. Etna that is characterized by evident morphological scarps and normal and right-lateral type movements that directly affect roads ...
Buried active faults in the Zafferana Etnea territory (south-eastern flank of Mt. Etna): geometry and kinematics by earthquake relocation and focal mechanisms
Seismic swarm Waveform correlation Precise relocation Fault plane geometry
2015/8/18
We relocated seismicity that occurred from 2000 to 2005 inside a sector of Mt. Etna, comprising the town of Zafferana Etnea, using the double-difference technique. This approach revealed some spatial ...
