High-resolution mapping and dispersion analyses of volcanic ballistics emitted during the 3rd July 2019 paroxysm at Stromboli
Geometry framework used for the analyses and including rings, sectors and reference elements. The number in bold black indicates the ring, and the number in bold red indicates the angular sector. The black circles (25 m of radius) represent the reference areas for analysing the variation of dispersion parameters along…

Volcanic Early Warning Using Shannon Entropy: Multiple Cases of Study
Temporal evolution of the Shannon entropy before and after four lava fountain paroxysms of Mt. Etna during November 2013 all of them marked with vertical red lines. Green region indicates a decay bigger than the 70%. Decay at the moment of the eruption: 98.4%, 98.9%, 97.4%, and 95.1%. Rey-Devesa P., C.
