Bulletin of Volcanology, 2021 Numerical results of a two-layer depth-averaged model of pyroclastic density currents (PDCs) were compared with an experimental PDC generated at the international eruption simulator facility (the Pyroclastic flow Eruption Large-scale Experiment (PELE ...

Reproducing pyroclastic density current deposits of the 79 CE eruption of the Somma–Vesuvius volcano using the box-model approach [PDF]
Solid Earth, 2021 We use PyBox, a new numerical implementation of the box-model approach, to reproduce pyroclastic density current (PDC) deposits from the Somma–Vesuvius volcano (Italy).

Frontiers in Earth Science, 2020 Pyroclastic density currents (PDCs) are a destructive volcanic hazard. Quantifying the types, frequency and magnitudes of PDC events is essential for effective risk management, but since historical records at best extend a few hundred years this usually ...

New developments in the analysis of column-collapse pyroclastic density currents through numerical simulations of multiphase flows [PDF]
Solid Earth, 2012 A granular multiphase model has been used to evaluate the action of differently sized particles on the dynamics of fountains and associated pyroclastic density currents.

Construction of probabilistic event trees for eruption forecasting at Sinabung volcano, Indonesia 2013-14 [PDF]
, 2019 Eruptions of Sinabung volcano, Indonesia have been ongoing since 2013. Since that time, the character of eruptions has changed, from phreatic to phreatomagmatic to magmatic explosive eruptions, and from production of a lava dome that collapsed to a ...

Generation of Overspill Pyroclastic Density Currents
, 2021 Pyroclastic density currents (PDCs) are composed of hot gas and glass like ash or rocks. They can be very mobile, flowing over obstacles with ease but their pathway is often controlled by the topography they flow over. When a PDC is confined to valley it increases the distance it can travel but the PDC can overflow from the valley unexpectedly ...

Earth, Planets and Space, 2018 A pyroclastic density current (PDC) was observed with the phreatomagmatic eruption of the Kuchinoerabujima volcano, southern Japan, on May 29, 2015. The PDC flowed down in all direction from the source crater, forming three major branches.

Volcanica, 2022 San Miguel (or Chaparrastique) volcano, El Salvador, erupted on the 29th December 2013, after almost 40 years of quiescence. Initial vent-clearing explosions ejected ballistic blocks and produced a pyroclastic density current (PDC) that flowed down the ...
