Dear Colleagues,
We’d like to draw your attention to our session II.1 Viscous Lava Flows and Domes: Multi-disciplinary Studies of Emplacement Mechanisms at the forthcoming IAVCEI 2017 meeting in Portland.
This session focuses on multi-disciplinary studies that explore the relationships between observations of viscous lava flows and domes, and models for their emplacement. Welcome contributions include field mapping of textures, structures and morphology; remote sensing of surfaces including LiDAR and thermal infrared; analog and numerical simulations; geophysical monitoring; and geochemistry of products. These will complement investigations of recently-active intermediate to silicic composition extrusions. A main goal is to blend studies of older flows whose behavior must be inferred with those of recent flows observed while active to answer questions such as: (1) What magma ascent conditions and physical properties regulate lava dome eruptions? (2) What mechanisms, processes and stress conditions trigger geophysical signals during dome eruptions? (3) What are the relationships among degassing, outgassing, magma permeability and lava surface textures and structures? (4) How does dome structural stability evolve through time? (5) What are potential triggers for dome failure and collapse? (6) How do we reconcile monitored data obtained at different acquisition rates and precision? (7) How does dome structure relate to conduit geometry?
Invited speakers:
Jonathan Castro, Johannes Gutenberg University of Mainz
Donald Dingwell, Ludwig Maximilians University of Munich
We hope to generate a dialogue between a broad spectrum of researchers, and hope you will consider contributing to our session – Which will also be preceded by a pre-conference field trip to Holocene-aged, dike-fed silicic flows in the Cascade Mountains of Oregon and California, USA (details at http://iavcei2017.org/ft_ha
Note that registration is now open at http://iavcei2017.org/regis
Kind Regards, and see you in Portland!
The Conveners: Steven Anderson, Jonathan Fink, Yan Lavallee, Jackie Kendrick & Ben Kennedy
