TLDR
In this article, the authors present a simplified 2D model for the flow of a Herschel-Bulkley fluid over an inclined plane with a constant flux from a vent, which they validate with analogue experiments scaled to typical conditions of lava flows.About:

Enhanced volcanic hot-spot detection using MODIS IR data: results from the MIROVA system
Diego Coppola,Marco Laiolo,Marco Laiolo,Corrado Cigolini,Dario Delle Donne,Dario Delle Donne,Maurizio Ripepe +6 more
TL;DR: In this paper, a new volcanic hotspot detection system, named Middle InfraRed Observation of Volcanic Activity (MIROVA), based on the analysis of infrared data acquired by the Moderate Resolution Imaging Spectroradiometer sensor (MODIS), is described.

Effects of crystal shape- and size-modality on magma rheology
P. Moitra,Helge M. Gonnermann +1 more
TL;DR: In this paper, a suite of shear viscosity measurements on liquid-particle suspensions of dynamical similarity to crystal-bearing magma was performed, and the results were fitted using a Herschel-Bulkley model and augment existing predictive capabilities.
Journal ArticleDOI
Examining rhyolite lava flow dynamics through photo-based 3D reconstructions of the 2011–2012 lava flowfield at Cordón-Caulle, Chile
TL;DR: In this paper, the authors used three-dimensional point clouds using structure-from-motion and multi-view stereo (SfM-MVS) freeware to reconstruct spatial distributions of lava velocity and depth, and estimate rheological parameters.
Journal ArticleDOI
A review of laboratory and numerical modelling in volcanology
TL;DR: A review of the use of laboratory and numerical modelling in volcanological research can be found in this paper, focusing on sub-surface and eruptive processes including the accretion and evolution of magma chambers, the propagation of sheet intrusions, the development of volcanic flows (lava flows, pyroclastic density currents, and lahars), volcanic plume formation, and ash dispersal.

The rheological evolution of the 2014/2015 eruption at Holuhraun, central Iceland
S. Kolzenburg,S. Kolzenburg,Daniele Giordano,Thorvaldur Thordarson,Ármann Höskuldsson,D. B. Dingwell +5 more
TL;DR: In this paper, the authors combine field and remote sensing data collected during the week of the 17th to 22nd of November 2014 to constrain the lava's flow path, its velocity, deformation rate and thermal evolution during emplacement.

Viscosity of magmatic liquids: A model
TL;DR: In this paper, a model that predicts the non-Arrhenian Newtonian viscosity of silicate melts as a function of T and melt composition, including the rheologically important volatile constituents H2O and F, is presented.

Viscosities of magmatic silicate liquids; an empirical method of prediction
TL;DR: In this article, it was shown that viscosities of anhydrous silicate liquids can be estimated more rapidly and with equal precision using only four partial molar coefficients of SiO 2.

On the crystallinity, probability of occurrence, and rheology of lava and magma
TL;DR: In this article, a histogram of the total phenocryst content measures the probability of the magma to be erupted as lava, and the eruption probability is defined as the product of the probability for finding the magmas at any state of crystallinity (thermal probability) and the rheological probability (Rpheological probability).
