Periodic volcanic degassing behavior: The Mount Etna example

A lava flow simulation model for the development of volcanic hazard maps for Mount Etna (Italy)

Volcanic hazard assessment is of paramount importance for the safeguard of the resources exposed to volcanic hazards. In the paper we present ELFM, a lava flow simulation model for the evaluation of the lava flow hazard on Mount Etna (Sicily, Italy), the most important active volcano in Europe. The major contributions of the paper are: (a) a detailed specification of the lava flow simulation mo...

Particle Geochemistry of Volcanic Plumes of Etna and Mount St. Helens

Particles in volcanic plumes forecasting [Rose et al., 1983]. The volcanogenic include vapor condensates and reaction products element fluxes provide a baseline for air of ash with vapors or condensed liquids, in pollution [e.g., Varekamp and Buseck, 1986]. addition to abundant silicate particles. In the In volcanic plumes, tiny particles form as a 1980 M•unt St. Helens plume we detected abunda...

Volcanic conduit migration over a basement landslide at Mount Etna (Italy)

The flanks of volcanoes may slide in response to the loading of the edifice on a weak basement, magma push, and/or to tectonic stress. However, examples of stratovolcanoes emplaced on active landslides are lacking and the possible effects on the volcano dynamics unknown. Here, we use aeromagnetic data to construct a three-dimensional model of the clay-rich basement of Etna volcano (Italy). We p...

Water in volcanic glass: From volcanic degassing to secondary hydration

Volcanic glass is deposited with trace amounts (0.1–0.6 wt.%) of undegassed magmatic water dissolved in the glass. After deposition, meteoric water penetrates into the glass structure mostly as molecular H2O. Due to the lower dD (‰) values of non-tropical meteoric waters and the 30‰ offset between volcanic glass and environmental water during hydration, secondary water imparts lighter hydrogen ...
