Abstract Themes
This Chapman is focusing on four main areas of the science to keep focus and show progression.
- 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?
- 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?
- 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?
- 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, and an optional post-conference field trip will visit lower East Rift Zone eruptive sites from 2018. 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
