Pyroclastic density currents (PDCs) are hazardous and destructive phenomena that pose a
significant threat to communities living in the proximity of active volcanoes. PDCs are ground …

This review summarizes what the volcanology community has learned thus far from studying
the deposits of pyroclastic currents (PCs) from the 1980 eruption sequence at Mount St …

Until recently, despite being one of the most important sediment transport phenomena on
Earth, few direct measurements of turbidity currents existed. Consequently, their structure …

Juvenile pyroclasts, especially in the ash size range, provide important information on
primary fragmentation processes, ie, initial explosive magma fragmentation, and on the state …

The estimation of the volume of volcanic flows during an ongoing eruption is challenging but
this information is crucial for improving risk assessment and for forecasting future events …

The morphometry of volcanic ash produced by explosive eruptions yields ample information
on fragmentation processes (eg magmatic vs magma–water interactions), and on transport …

Pyroclastic currents are very destructive and their complex behavior makes the related
hazards difficult to predict. A new numerical model has been developed to simulate the …

Pyroclastic density currents (PDCs) are a significant volcanic hazard. However, their
dominant transport mechanisms remain poorly understood, in part because of the large …

Seventeen pyroclastic density currents (PDCs) were produced before, during and after the
Plinian phase of the ad 79 eruption of Vesuvius. Their deposits were correlated using the …

We have used a three-dimensional, non-equilibrium multiphase flow numerical model to
simulate subplinian eruption scenarios at La Soufrière de Guadeloupe (Lesser Antilles …
