A high-resolution forecast methodology for the ash hazard at Sakurajima volcano, Japan, is
presented. The methodology employs a combined modeling approach and utilizes eruption …

The evolution of sand jets passing through an immiscible layer and entering water was
experimentally investigated to understand the effects of controlling parameters on the …

The threat posed by powerful Plinian explosive eruptions, which inject large quantities of
ash into the atmosphere and produce pyroclastic density currents (PDC) on ground, is …

Laboratory experiments were conducted to study the dynamics of particle clouds in viscous
fluids. Different shapes of frontal head and trailing stems were observed, and particle clouds …

Major volcanic hazards in the Lesser Antilles arc include powerful Plinian explosive
eruptions that inject ash high into the atmosphere and produce dangerous pyroclastic …

The rate at which atmosphere is entrained and mixed into relatively dense explosive
volcanic jets of gas and pyroclasts (ash, lapilli) determines whether they rise into the …

Volcanic plumes from small and moderate eruptions represent a challenge in the study of
plume morphology due to eruption source parameter uncertainties and atmospheric …

Sand jets and particle clouds in water and viscous fluids have been a frequent subject of
intense research and are pertinent to many environmental, industrial, and engineering …
