Evaluation of topographic effects on infrasonic array observation toward the source elevation estimation

Earth, Planets and Space
The infrasonic array technique is applied in many volcanoes to locate the acoustic source. Compared to the azimuthal estimation for the horizontal source location information, the elevational estimation is challenging due to the difficulty of aligning ...

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 ...

Enhancing the uncertainty quantification of pyroclastic density current dynamics in the Campi Flegrei caldera.

, 2019
In this study we present a new effort to improve the uncertainty quantification (UQ) of pyroclastic density current dynamics in the Campi Flegrei caldera, thanks to the implementation of a new 2D depth-averaged granular flow model in the Monte Carlo ...

Characteristics of submarine pumice-rich density current deposits sourced from turbulent mixing of subaerial pyroclastic flows at the shoreline: field and experimental assessment

, 2012
This study investigates the types of subaqueous deposits that occur when hot pyroclastic flows turbulently mix with water at the shoreline through field studies of the Znp marine tephra in Japan and flume experiments where hot tephra sample interacted ...
