The ad 79 Vesuvius eruption revisited: the pyroclastic density currents

Journal of the Geological Society
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 proportions of components, together with the recognition of distinctive intercalated regionally traceable fall marker layers, revealing ...

Unravelling the Mystery of Pyroclastic Density Currents by Synthesizing Field Observations with Analogue Laboratory Experiments

, 2019
Pyroclastic density currents (PDCs) are gravity-driven avalanches of gas and solid particles that occur during volcanic eruptions. PDCs happen with little warning and travel long distances at high velocities, making them one of the most significant ...
