Eruption column modeling of explosive volcanism on Venus

Plume neutral buoyancy altitude (left column) and maximum altitude (right column) in relation to the MFR, exit temperature and exit velocity at an elevation of 4 km (top row) and 8 km (bottom), both at the Equator with wind shear and for an atmospheric heat capacity varying with temperature and a pyroclast…

Volcanism on Venus

SEMINARIO: Speaker: Maxence LefevreAffiliation: CNRS, LATMOSDate: 23th October 2025Time: 14:30Hosted by: INGV Sezione di Pisa Abstract Abstract: Earth and Venus are similar in size and mass, but there are major differences between their atmospheres. On Venus, no climate variability has been clearly demonstrated. On the surface…

Post-caldera eruptions at the Valles Caldera, New Mexico (USA)

SEMINARIO: Speaker: Amanda ClarkeAffiliation: Arizona State University (School of Earth and Space Exploration)Date: 13th December 2023Time: 11:00 AMHosted by: INGV Sezione di Pisa Abstract Many calderas remain restless after large-volume eruptions, and Valles caldera is a classic example of a restless, resurgent caldera. The Valles caldera…

Assessment of eruption source parameters using infrasound and plume modelling: a case study from the 2021 eruption of Mt. Etna, Italy

Model and satellite image of the ash plume during paroxysmal activity at Mt. Etna on 20 June, 2023. (a) Map view of the modelled plume showing ash drifting towards the East; (b) Cross-section (West–East) view of the modelled plume for values of flow velocity of 50, 75 and 125 m/s. Solid…
