Introduction to Special Issue of Bulletin of Volcanology on “Advances in Kimberlite Geology and Volcanology” [PDF]
Bulletin of Volcanology, 2011 The volcanology of kimberlite pipes and volcanoes has been a neglected area of mainstream volcanology research, until the last several years. Previously, published kimberlite research focused largely on petrological and geochemical aspects, with few studies on the physical eruption processes, the volcanic facies characteristics and their volcanological

Atmospheric electrification in dusty, reactive gases in the solar system and beyond [PDF]
, 2016 Detailed observations of the solar system planets reveal a wide variety of local atmospheric conditions. Astronomical observations have revealed a variety of extrasolar planets none of which resembles any of the solar system planets in full. Instead, the most massive amongst the extrasolar planets, the gas giants, appear very similar to the class of ...

Molecular-Dynamics Simulation of Vulcanian Eruption [PDF]
arXiv, 2005 Vulcanian explosive eruption, which is a nonlinear and nonequilibrium abrupt dynamics of magma-gas mixture, is modeled by a two-component Lennard-Jones particle system. Molecular-dynamics simulation of a shock-tube experiment gives consistent results with a explosive eruption picture of volcanology; Shock wave and expansion wave are reproduced.

Estimation and uncertainty quantification of magma interaction times using statistical emulation
VolcanicaThe evolution of volcanic plumbing systems, which controls the style and size of eruptions, is largely determined by processes at depths that are not observable.

Edge Detection in Radar Images Using Weibull Distribution [PDF]
arXiv, 2013 Radar images can reveal information about the shape of the surface terrain as well as its physical and biophysical properties. Radar images have long been used in geological studies to map structural features that are revealed by the shape of the landscape.

Subsidence and current strain patterns on Tenerife Island (Canary Archipelago, Spain) derived from continuous GNSS time series (2008-2015) [PDF]
Journal of Volcanology and Geothermal Research 327 (2016) 240 -
248In this paper we present the current crustal deformation model of Tenerife Island derived from daily CGPS time series processing (2008 to 2015). Our results include the position time series, a global velocity estimation and the current crustal deformation on the island in terms of strain tensors. We detect a measurable subsidence of 1.5 to 2 mm/yr.

Effects of magma-induced stress within a cellular automaton model of volcanism [PDF]
, 2017 The cellular automaton model of Piegari, Di Maio, Scandone and Milano, J. Volc. Geoth. Res., 202, 22-28 (2011) is extended to include magma-induced stress (i.e. a local magma-related augmentation of the stress field). This constitutes a nonlinear coupling between the magma and stress fields considered by this model, which affects the statistical ...

A Nineteen Day Earth Tide Measurement with a MEMS Gravimeter [PDF]
arXiv, 2021 The measurement of tiny variations in local gravity enables the observation of subterranean features. Gravimeters have historically been extremely expensive instruments, but usable gravity measurements have recently been conducted using MEMS (microelectromechanical systems) sensors.
