The collapse and decrepitation of a lava dome at the summit of a volcano generally results
in the generation of dense granular flows, often referred to as block and ash flows. As the …

Volcanic plumes are turbulent mixtures of particles and gas which are injected into the
atmosphere during a volcanic eruption. Depending on the intensity of the eruption, plumes …

Abstract Total Grain-Size Distribution (TGSD) of tephra deposits is key to the
characterization of explosive volcanism, plume-dispersal modeling, and magmatic …

Emplacement dynamics of highly viscous, silicic lava flows remain poorly constrained due to
a lack of consideration of crystal-rich cases. Emplacement models mostly apply to glassy or …

We present the first experimental investigation of the fragmentation behavior of two-phase
(melt+ gas) rhyolitic systems under rapid decompression. Two-phase samples have been …

Abstract Between 30 August and 15 December 2006, Mt Etna, Italy, underwent both effusive
and explosive activity which took place from the South-East Crater, one of its summit craters …

In this paper, we present results of the reconstruction of the total grain size distribution
(TGSD) of the material erupted during explosive volcanic eruptions at Campi Flegrei (Italy) …

Of all the key parameters needed to inform forecast models for volcanic plumes, real-time
tracking particle size distribution (PSD) of pyroclasts leaving the vent coupled with plume …

We have measured grain size distributions of the results of laboratory decompression
explosions of volcanic rock. The resulting distributions can be approximately represented by …

Abstract The stratovolcano Mt. Pelée, Martinique, exhibits eruptive styles ranging from dome
formation to sustained, highly violent explosive activity. Historical eruptions have produced …
