Assessment of motion-induced fluidization of dense pyroclastic gravity currents
pyroclastic flow fluidization gravity current
2015/9/10
The paper addresses some fundamental aspects of the dynamics of dense granular flows down inclines relevant
to pyroclastic density currents. A simple mechanistic framework is presented to analyze the...
Surface roughness of pyroclastic deposits at Mt. Etna by 3D laser scanning
surface roughness pyroclastic deposits Laser 3D
2015/9/1
The terrestrial 3D Laser Scanning technique has been applied to analyse the surface roughness of pyroclastic deposits on volcanic surfaces at Mt. Etna. This technique allowed the construction of high ...
New developments in the analysis of column-collapse pyroclastic density currents through numerical simulations of multiphase flows

Fall-experiments on Merapi basaltic andesite and constraints on the generation of pyroclastic surges
Fall-experiments Merapi basaltic andesite constraints pyroclastic surges
2010/9/28
We have performed fall-experiments with basaltic andesite rock samples from Merapi volcano, using an apparatus designed to analyze samples heated up to 850°C. Relative pressure changes during impact a...
