Caldera-Rift Systems and New Insights into Basaltic Volcano Dynamics

Session ID#: 74702

Session Description:
Recent observations of coupled rift intrusions/eruptions and summit collapses at basaltic volcanoes offer new opportunities to improve understanding of caldera formation, summit-rift magmatic connections, flank instability, lava lake dynamics, and the petrologic fingerprints of magmatic ascent, storage, and mixing. At the same time, monitoring data have improved the scientific community’s ability to issue hazard forecasts during eruptions. This session invites contributions that provide insights into basaltic caldera-rift systems across all disciplines, utilizing geological (field-based, petrological, geochemical) and geophysical observations, as well as experimental and theoretical models. Drawing on observations of commonalities between caldera collapses at Kīlauea, Bárdarbunga, Piton de la Fournaise, and elsewhere, we particularly invite studies that draw on interdisciplinary observations to understand the architecture of magmatic systems and physical processes during rift intrusions/eruptions and caldera collapses, and/or those that detail the use of real-time data in hazard management.
