Asymptotic Expansion for Harmonic Functions in the Half-Space with a Pressurized Cavity [PDF]
, 2015 In this paper, we address a simplified version of a problem arising from volcanology. Specifically, as reduced form of the boundary value problem for the Lam\'e system, we consider a Neumann problem for harmonic functions in the half-space with a cavity $C$.

New Insight on the Increasing Seismicity during Tenerife's 2004 Volcanic Reactivation [PDF]
Journal of Volcanology and Geothermal Research 206 (2011), 15-29, 2012 Starting in April 2004, unusual seismic activity was observed in the interior of the island of Tenerife (Canary Islands, Spain) with much evidence pointing to a reawakening of volcanic activity. This seismicity is now analyzed with techniques unprecedented in previous studies of this crisis. The 200 earthquakes located onshore during 2004 and 2005 have

Existence theorem for homogeneous incompressible Navier-Stokes equation with variable rheology [PDF]
, 2016 We look at a homogeneous incompressible fluid with a time and space variable rheology of Bingham type, which is governed by a coupling equation. Such a system is a simplified model for a gas-particle mixture that flows under the influence of gravity. The main application of this kind of model is pyroclastic flows in the context of volcanology. In order

Evidences for higher nocturnal seismic activity at the Mt. Vesuvius [PDF]
Journal of Volcanology and Geothermal Research 321, 102-113, 2016, 2016 We analyze hourly seismic data measured at the Osservatorio Vesuviano Ovest (OVO, 1972-2014) and at the Bunker Est (BKE, 1999-2014) stations on the Mt. Vesuvius. The OVO record is complete for seismic events with magnitude M > 1.9. We demonstrate that before 1996 this record presents a daily oscillation that nearly vanishes afterwards.

Small-area Portable Resistive Plate Chambers for Muography [PDF]
arXiv, 2023 Muography is finding applications in various domains such as volcanology, archaeology, civil engineering, industry, mining, and nuclear waste surveys. To simplify transportation and installation in remote locations after laboratory testing, a fully portable and autonomous muon telescope based on Resistive Plate Chambers (RPCs) is being developed.

3D density structure and geological evolution of Stromboli volcano (Aeolian Islands, Italy) inferred from land-based and marine gravity data [PDF]
Journal of Volcanology and Geothermal Research, 273, 58-69 (2014), 2017 We present the first density model of Stromboli volcano (Aeolian Islands, Italy) obtained by simultaneously inverting land-based (543) and sea-surface (327) relative gravity data. Modern positioning technology, a 1 * 1 m digital elevation model, and a 15 * 15 m bathymetric model made it possible to obtain a detailed 3-D density model through an ...

Deformation of a Half-Space from Anelastic Strain Confined in a Tetrahedral Volume [PDF]
, 2018 Deformation in the lithosphere-asthenosphere system can be accommodated by faulting and plastic flow. However, incorporating structural data in models of distributed deformation still represents a challenge. Here, I present solutions for the displacements and stress in a half-space caused by distributed anelastic strain confined in a tetrahedral volume.
