Tephra transport models try to predict atmospheric dispersion and sedimentation of tephra
depending on meteorology, particle properties, and eruption characteristics, defined by …

Explosive volcanic eruptions inject variable amounts of particles of variable size, shape, and
composition (ie, tephra) into the atmosphere. Tephra dispersal and sedimentation mostly …

Tephra erupted in volcanic plumes can be transported over distances of thousands of
kilometers, causing respiratory problems to humans and animals, serious damage to …

Our understanding of the spread of volcanic ejecta from eruption columns has evolved
significantly since the first quantitative studies. Given recent advances, it is possible to …

Ash3d is a three-dimensional Eulerian atmospheric model for tephra transport, dispersal,
and deposition, written by the authors to study and forecast hazards of volcanic ash clouds …

We perform a parametric and comparative study on three different tephra dispersal models
(FALL3D, HAZMAP, and TEPHRA) applied to two different scenarios expected for Etna …

A simple semianalytical model to simulate ash dispersion and deposition produced by
sustained Plinian and sub-Plinian eruption columns based on the 2D advection–dispersion …

Sensitivity analysis and uncertainty estimation are crucial to the validation and calibration of
numerical models. In this paper we present the application of sensitivity analyses, parameter …

Depending on their magnitude and location, volcanic eruptions have the potential to
become major social and economic disasters (eg Tambora, Indonesia, 1815; Vesuvius, Italy …

We develop descriptions of the key processes influencing tephra dispersal from strong
volcanic plumes. These are characterized by the development of a subvertical eruption …
