Complex magmatic systems and geophysical signal analysis: what can we understand from inversions?
14 Mar 2014 | Contributor(s): Chiara Paola Montagna, G. Saccorotti, P. Papale, A. Longo
Many volcanic eruptions are shortly preceded by new magma injection into a pre-existing, shallow (< 10 km) magma chamber, causing convection and mixing between the incoming and resident magmas. These processes may trigger dyke propagation and further magma rise, inducing long-term (days to...

Confort 15 (Conflow improvement)
20 Jan 2015 | Offline Tools | Contributor(s): Silvia Campagnola, Claudia Romano, Larry G Mastin, Alessandro Vona
We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...

Constraining conditions for phreatic eruptions and evaluating the influence of hydrothermal alteration on the process: an experimental approach (Vuelco mini conference Barcelona 2013)
20 Mar 2013 | Presentations | Contributor(s): Klaus Mayer, Betty Scheu
Phreatic eruptions are caused by rapid evaporation of hydrothermal fluids to steam with the resulting pore overpressure leading to fragmentation of overlying rocks.We investigate White Island (New Zealand) and the active volcanic sites Solfatara and Monte Nuovo in Campi Flegrei (Italy); further...

Constraining edifice stability and phreatic eruptions at White Island, New Zealand (CoV 7 2012)
20 Mar 2013 | Presentations | Contributor(s): Klaus Mayer, Betty Scheu
White Island is New Zealand's most active volcano and is primarily characterised by phreatic and phreatomagmatic eruptions, interspersed by occasional strombolian events. The common occurrence of magma-water interaction at White Island derives from the presence hydrothermal system that induces...

COV7 Workshop W2: Volcano Monitoring Techniques
14 Dec 2012 | Workshops | Contributor(s): Jeffrey Johnson, Nick Varley, Eliza S Calder, Gregory Waite, Jo Gottsmann, Simon Carn
Innovation in volcano monitoring techniques is rapid. In the search for eruption precursors, the more traditional areas of seismicity, geodesy and geochemistry are now routinely complemented by studies of acoustic or thermal emission. We are also beginning to better understand the significance of...
