We introduce a novel analytical expression that allows for fast assessment of mass flow rate
of both vertically‐rising and bent‐over volcanic plumes as a function of their height, while …

A simple three-dimensional volcanic plume model that incorporates the effects of moisture
and ambient wind is presented and used iteratively to refine the source mass flux, obtained …

During volcanic eruptions, empirical relationships are used to estimate mass eruption rate
from plume height. Although simple, such relationships can be inaccurate and can …

The mass eruption rate feeding a volcanic plume is commonly estimated from its maximum
height. Winds are known to affect the column dynamics causing bending and hence …

Estimates of volcanic source mass flux, currently deduced from observations of plume
height, are crucial for ash dispersion models for aviation and population hazard. This study …

We develop a transient, 3‐D Eulerian model (Ash3d) to predict airborne volcanic ash
concentration and tephra deposition during volcanic eruptions. This model simulates …

We introduce a new method to estimate mass eruption rate (MER) and mass loading from
the growth of a volcanic umbrella cloud or downwind plume using satellite images, or …

The collapse of volcanic plumes has significant implications for eruption dynamics and
associated hazards. We show how eruptive columns can collapse and generate pyroclastic …

Volcanic ash clouds are common, often unpredictable, phenomena generated during
explosive eruptions. Mainly composed of very fine ash particles, they can be transported in …

Data on source conditions for the 14 April 2010 paroxysmal phase of the Eyjafjallajökull
eruption, Iceland, have been used as inputs to a trajectory-based eruption column model …
