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 …

The electrification of volcanic plumes has been described intermittently since at least the
time of Pliny the Younger and the 79 AD eruption of Vesuvius. Although sometimes …

Observations of flowing granular matter have suggested that same-material tribocharging
depends on particle size, typically rendering large grains positive and small ones negative …

Soon after the onset of an eruption, model forecasts of ash dispersal are used to mitigate the
hazards to aircraft, infrastructure, and communities downwind. However, it is a significant …

In dispersed two-phase flows, particle electrification is a prevalent phenomenon that plays a
crucial role in particle transport. However, the influences of electrostatic forces on particle …

The 2016–2017 shallow submarine eruption of Bogoslof volcano in Alaska injected plumes
of ash and seawater to maximum heights of~ 12 km. More than 4550 volcanic lightning …

While the electrification of dust storms is known to substantially affect the lifting and transport
of dust particles, the electrical structure of dust storms and its underlying charge separation …

Abstract Hunga Tonga-Hunga Ha'apai (HTHH), a submarine caldera volcano of the Tonga
archipelago, erupted explosively on January 15, 2022. The eruption generated the highest …

Atmospheric transport and suspension of dust frequently brings electrification, which may be
substantial. Electric fields of 10 kV m− 1 to 100 kV m− 1 have been observed at the surface …

The scientific investigation of magma fragmentation and the development of experiments to
constrain and quantify its mechanisms, dynamics, efficiency and products was ushered in …
