  Information - GMPV23 Explosive activity at basaltic volcanoes

Event Information
Explosive eruptions of mafic to intermediate magmas possibly represent the most frequent type of volcanic activity worldwide. Due t its specific physic-chemical properties, mafic magmas produce specific eruptive scenarios in respect to its more felsic counterpart, including the bursting of gas slugs, multifarious explosive interaction external fluids, annular gas flow, and fast foaming of volatile-saturated melt. From an observational and monitoring point of view, basaltic explosive activity is relatively accessible, and an important challenge for the future is how multiparametric records from well-observed basaltic explosions may provide a basis for volcanic explosion theories that apply also to less accessible eruptions. Finally, from an hazard-related point of view, specific hazards are associated with low-intensity basaltic activity, with harmful events like the fallout of ballistic ejecta, paroxysmal explosions, and violent magma-water interaction that often, and unexpectedly, punctuate relatively harmless and prolonged low-level Strombolian and lava flow activity. Here we propose an interdisciplinary session to cover the above (and possibly other) aspects proper of explosive activity at basaltic volcanoes, with particular emphasis to works that integrate field, experimental, and analytical approaches as well as novel technologies.
