Probabilistic hazard maps of dilute pyroclastic density current at Vesuvius
, 2023 Dilute pyroclastic density currents are one major source of hazard at Vesuvius. By combining data of deposits of the explosive eruptions of the last six thousand years and interpolating data of impact parameters (Velocity, Density, particle volumetric concentration, temperature, dynamic pressure), which were calculated by modeling the currents as ...

A Hidden Eruption: The 21 May 2023 Paroxysm of the Etna Volcano (Italy)
Remote SensingOn 21 May 2023, a hidden eruption occurred at the Southeast Crater (SEC) of Etna (Italy); indeed, bad weather prevented its direct and remote observation.

Differentiation of Planetesimals and the Thermal Consequences of Melt Migration
, 2011 We model the heating of a primordial planetesimal by decay of the short-lived radionuclides Al-26 and Fe-60 to determine (i) the timescale on which melting will occur; (ii) the minimum size of a body that will produce silicate melt and differentiate ...

Igneous processes within late Precambrian volcanic centres near Whitwick, northwestern Charnwood Forest [PDF]
, 2000 Precambrian rocks in northwestern Chamwood Forest differ markedly from their lateral equivalents to the east and south. They are subdivided into the Whitwick Volcanic Complex, of massive to intensely brecciated high-silica andesites and porphyritic ...

, 2005 The kinematic and dynamic scaling of dilute multiphase mixtures in magmatic systems is the only guarantee for the geological verisimilitude of laboratory experiments. We present scaling relations that can provide a more complete framework to scale dilute

Proceedings of a workshop on Lunar Volcanic Glasses: Scientific and Resource Potential [PDF]
This workshop on lunar mare volcanism was the first since 1975 to deal with the major scientific advances that have occurred in this general subject, and the first ever to deal specifically with volcanic glasses.

Connecting with tephras: principles, functioning, and applications of tephrochronology in Quaternary science [PDF]
, 2013 Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects
