Boom, Zap, and Roar: Multi-disciplinary characterization of volcanic explosion, jet, and plume dynamics
Session ID#: 81555
Session Description:
Explosive volcanic eruptions generate highly electrified, multi-phase momentum-driven fluid flows (jets) that can transform into buoyant plumes. Understanding the dynamics of these systems is critical for forecasting eruption behavior and interpreting geophysical and visual observations of the jets and plumes. Unfortunately, these eruptions present numerous hazards and the interiors of the jets and plumes are obscured from direct observation. In this session we welcome submissions that discuss the dynamics of explosive eruption processes from generation to cessation with particular foci on processes that occur in the jet and plume, such as how lightning manifests in a jet or plume, particle concentration gradients and aggregation, turbulent structures, etc. We are particularly interested in studies that use field observations (e.g., seismicity, infrasound, gas, visible, infrared, and UV imagery, lightning, radar, deformation), laboratory and analog experiments, and/or physics-based modeling.
