The electrification of volcanic ash plumes and the occurrence of volcanic lightning are now
known to be common phenomena during explosive volcanic eruptions. This knowledge …

It has been 10 years since the ash cloud from the eruption of Eyjafjallajökull caused
unprecedented disruption to air traffic across Europe. During this event, the London Volcanic …

The 39-day long eruption at the summit of Eyjafjallajökull volcano in April–May 2010 was of
modest size but ash was widely dispersed. By combining data from ground surveys and …

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 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 …

Eruptive column models are powerful tools for investigating the transport of volcanic gas and
ash, reconstructing past explosive eruptions, and simulating future hazards. However, the …

A fully automated, globally applicable algorithm to retrieve ash and dust cloud properties
from infrared satellite measurements is presented. The algorithm, which will serve as the …

During the 2010 eruption of Eyjafjallajökull, improvements were made to the modeling
procedure at the Met Office, UK, enabling peak ash concentrations within the volcanic cloud …

During operational ash-cloud forecasting, prediction of ash concentration and total erupted
mass directly depends on the determination of mass eruption rate (MER), which is typically …

This paper discusses how epistemic uncertainties are currently considered in the most
widely occurring natural hazard areas, including floods, landslides and debris flows, dam …
