Finite element analysis of ground deformation due to dike intrusion with applications to Mt. Etna volcano

Annals of Geophysics, 2004
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 (dimension domain, elements type) was calibrated using plane

Fine‐Scale Structure and Kinematics of an Active Submarine Strike‐Slip Fault From Micro‐Bathymetric Mapping and Analog Modeling: The North Alfeo Fault Offshore Catania (Eastern Sicily)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Southern Italy and eastern Sicily have been the site of several destructive historical earthquakes. Here at the junction between the western edge of the Calabrian subduction zone and the Malta Escarpment several strike‐slip faults have been mapped, which may be the surface expression of the lateral slab tear fault and are candidate sources for

Controls on Magma Output From Stromboli's Plumbing System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Quantifying magma output over variable timescales is essential for understanding persistently active volcanoes. We analyze magma output at Stromboli (during 2000–2025) using satellite thermal data integrated with a comprehensive database of volcanic activity.

Numerical simulation of stress induced piezomagnetic fields at Etna volcano

, 2009
3-D magneto-elastic models based on finite element method (FEM) have been developed to compute piezomagnetic fields caused by magmatic overpressure sources.We solved separately (i) the elastostatic equation for the stress field and (ii) the coupled ...

Valle del Bove, Eastern Flank of Etna Volcano: a Comprehensive Model for the Opening of the Depression and Implications for Future Hazards

, 2004
In this paper we integrate stratigraphic and sedimentological analyses of the volcaniclastic deposits, emplaced during initial opening and later widening of the Valle del Bove depression, with the available stratigraphy of the inner walls, and marine ...

Lava flows of Mt Etna, Italy: the 2019 eruption within the context of the last two decades (1999–2019)

Journal of Maps, 2021
UAVs have become a useful tool for natural hazard monitoring. In volcanic areas, they allow wider observations of the eruptive behaviour, with no risk for the operator.

Volcanism at Piton de la Fournaise as an Analog for Chloris Mons, Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Identifying and investigating terrestrial analogs for Venus volcanic activity is necessary to prepare for the planned upcoming missions to Venus. We propose volcanism at Piton de la Fournaise, a frequently active oceanic shield volcano, as an analog to volcanism at Chloris Mons, Venus.

Structural assessment of Mount Etna volcano from Permanent Scatterers analysis

, 2011
A study of the deformation pattern of Mount Etna volcano based on the results from the Permanent Scatterers (PS) technique is reported. Ground motion data provided by the interferometric synthetic aperture radar (InSAR) PS technique from 1995 to 2000 ...

Eruptions of Mt Etna during the past 3.200 years: a revised compilation integrating the Historical and stratigraphic records.

, 2004
For thousands of years man has marvelled at the gigantic structure that makes up Mt. Etna, the largest active volcano in Europe, and has lived side by side with the mountain, which despite its intense eruptive activity has always been considered a ...

Application of Data Assimilation Methods to Reconstruct the 3–5 December 2015 Etna Eruption

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The assessment of volcanic hazards is crucial to develop effective emergency plans, especially for volcanoes close to urban areas or under air traffic routes. Impact assessment for expected scenarios relies on underlying numerical models that require eruption source parameters as inputs, and forecasts drastically depend on their robust ...
