Multiphase flow behaviour and hazard prediction of pyroclastic density currents
Pyroclastic density currents (PDCs) are dangerous multiphase flows originating from
volcanic eruptions. PDCs cause more than a third of volcanic fatalities globally and …

Seismic and acoustic signatures of surficial mass movements at volcanoes
Surficial mass movements, such as debris avalanches, rock falls, lahars, pyroclastic flows,
and outburst floods, are a dominant hazard at many volcanoes worldwide. Understanding …

The fragmentation-induced fluidisation of pyroclastic density currents
Pyroclastic density currents (PDCs) are the most lethal volcanic process on Earth.
Forecasting their inundation area is essential to mitigate their risk, but existing models are …

Hydrothermal alteration of andesitic lava domes can lead to explosive volcanic behaviour
Dome-forming volcanoes are among the most hazardous volcanoes on Earth. Magmatic
outgassing can be hindered if the permeability of a lava dome is reduced, promoting pore …

Deposits from dome-collapse and fountain-collapse pyroclastic flows at Soufrière Hills Volcano, Montserrat
Pyroclastic flows were formed at Soufrière Hills Volcano by lava-dome collapse and by
fountain collapse associated with Vulcanian explosions. Major episodes of dome collapse …
