Assessing minimum pyroclastic density current mass to impact critical infrastructures: example from Aso caldera (Japan)
Bevilacqua, Andrea; Aravena, Alvaro; Aspinall, Willy; Costa, Antonio; Mahony, Sue; Neri, Augusto; Sparks, Stephen; Hill, Brittain (2022)We describe a method for calculating the probability that a distal geographic location is impacted by a pyroclastic density current (PDC) of a given size, considering the key related uncertainties. Specifically, we evaluate ...

Morphology-based characterization of intermediate to silicic lava flows: application to the central andean volcanic zone
Sepulveda, Jose Pablo; Cioni, Raffaello; Aravena, Alvaro (2023)The morphology of a lava flow records the eruptive dynamics that governed its emplacement, evolution, and the rheological properties of the erupted magma. Although the dynamics and morphological classification of mafic ...

Toward a real-time analysis of column height by visible cameras: an example from mt. Etna, in Italy
Aravena, Alvaro; Carparelli, Giuseppe; Cioni, Raffaello; Prestifilippo, Michele; Scollo, Simona (2023)Volcanic plume height is one the most important features of explosive activity; thus, it is a parameter of interest for volcanic monitoring that can be retrieved using different remote sensing techniques. Among them, ...
