Dynamic Statistical Models for Pyroclastic Density Current Generation at Soufrière Hills Volcano

Frontiers in Earth Science, 2018
To mitigate volcanic hazards from pyroclastic density currents, volcanologists generate hazard maps that provide long-term forecasts of areas of potential impact. Several recent efforts in the field develop new statistical methods for application of flow

Seismic characterization of pyroclastic flow activity at Soufrière Hills Volcano, Montserrat, 8 January 2007 [PDF]

Natural Hazards and Earth System Sciences, 2007
A partial dome collapse with concurrent pyroclastic flow (PF) activity occurred at Soufrière Hills Volcano (SHV), Montserrat on 8 January 2007. Pyroclastic density currents were observed to propagate from the Northwest and West sectors of the summit dome

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 ...

Eruption and deposition of the fisher tuff (Alaska) : evidence for the evolution of pyroclastic flows.

, 2007
International audienceRecognition that the Fisher Tuff (Unimak Island, Alaska) was deposited on the leeside of ~500-700 m high mountain range (Tugamak Range) more than 10 km away from its source played a major role in defining pyroclastic flows as ...
