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...
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...
Finite element modeling of ground deformation and gravity field at Mt. Etna
numerical modeling gravity anomaly
2015/9/1
An elastic 3-D axi-symmetric model based on Finite Element Method (FEM) is proposed to compute ground deformation
and gravity changes caused by overpressure sources in volcanic areas. The numerical c...
Structural analysis of the eruptive fissures at Mount Etna (Italy)
Eruptive fracture dike Magmas Tectonics Structural geology
2015/8/27
Mount Etna produces frequent eruptions from its summit craters and from fissures on its flanks. The flank fissures trend approximately radially to the summit, and are mainly concentrated in three rift...
The flank eruption history of Etna (1610-2006) as a constraint on lava flow hazard
flow hazard Etna
2015/8/27
Data of the flank eruptions of Etna from over the last 400 years were extracted from the new geological map for the lava flow extensions and vent positions, and from the catalogs of historical eruptio...
Quantitative analysis of the 1981 and 2001 Etna flank eruptions: a contribution for future hazard evaluation and mitigation
flank eruptions future hazard evaluation and mitigation
2015/8/27
Lava flows produced during Etna flank eruptions represent severe hazards for the nearby inhabited areas, which can be protected by adopting prompt mitigation actions, such as the building of diversion...
High-precision gravity measurements using absolute and relative gravimeters at Mount Etna (Sicily, Italy)
