What are the important observations during historical caldera-rift eruptions?
What are the key similarities and differences?
What triggers these eruptions?
What are the inferences for the growth of basaltic shield volcanoes?
What are some of the obvious outstanding questions?
Theme 2: Coupled magmatic-tectonic caldera-rift systems
How does magma accumulate and flow in basaltic rift zones?
How do coupled magmatic-tectonic systems lead to large CREs?
What do we know about magma storage in volcanic rifts, and what are the implications for hazards?
What are the geometry and physical properties of magma in subcaldera reservoirs, how do these properties affect caldera collapses, and how are these bodies connected with rift zones?
Where did Kilauea’s 2018 lavas come from?
What insights do caldera collapses give into nonvolcanic earthquakes?
Do we understand the physics and dynamics of caldera collapses?
Why do basaltic collapses occur episodically?
What role for preexisting structures play in collapses?
Theme 3: Eruptive processes, hazards, and forecasting
How does summit-rift feedback influence how much material will be erupted and what influences the volume and rate of effusion?
How can lava flow and other hazard be reforecast during eruptions when changing conditions in either summit or rift might influence the surface activity?
How does pre-eruptive magma storage and evolution of its physical properties influence the eruptive activity at the surface?
How can different monitoring datasets, including near-real-time petrologic and geochemical monitoring, be leveraged to understand the evolution of CREs and their associated hazards?
Theme 4: The post-collapse period and the evolution of caldera-rift systems
How did the 2018 eruption change Kilauea and other Hawaiian volcanoes, and how do these volcanoes interact with one another?
What have we learned from Kilauea’s post-2018 eruptions? Recovery after other basaltic collapses?
How can post-caldera collapse eruptions help us understand changes in plumbing system geometry and connectivity?
What are the immediate vs. long term impacts of caldera collapse, and how do these impacts vary among different volcanic systems globally?
How does understanding post-collapse changes to volcanic systems help to update and develop actionable hazard forecasts for partner agencies?
Format Overview
A Sunday evening icebreaker will be followed by an opening convocation on Monday morning. Monday, Tuesday, Thursday, and Friday will feature a mix of invited keynote presentations, contributed talks and posters, working group breakouts, and workshops and panels. A mid-conference field trip on Wednesday will visit Kīlauea’s summit caldera. Session topics include:
Session 1: Recorded caldera-rift eruptions and open questions
Session 2: Coupled magmatic-tectonic systems
Session 3: Eruptive processes, hazards, and forecasting
Session 4: The post-collapse period and the evolution of caldera-rift systems
