V31: Lava Flow Dynamics and Morphology: Integrating Field, Laboratory
and Theoretical Studies
Session Abstract:
Understanding the dynamics and morphology of active lava flows, lakes
and domes requires field study, laboratory-based measurements and
theoretical treatment. Field studies allow us to define, describe and
parameterize characteristic phenomena, such as emplacement styles,
velocities, and heat/mass fluxes, as well as associated flow regimes,
morphologies and their characteristic dimensions and time scales. New
insights have been made possible by field deployment of stereo-pairs of
high resolution digital-cameras, ground-based laser and LiDAR
measurements, plus hand-held thermal imagers. Laboratory studies allow
definition of characteristic crystallization rates and vesicularities,
as well as compositional, temperature, vesicle and crystal dependent
rheology. Finally, theoretical treatments allow the physics and
dynamics of flow emplacement to be defined. This session seeks to
review our current understanding of active lava emplacement through
integration of field study, laboratory-based measurements and
theoretical modeling.
Please note that the abstract submission deadline is 6 September 2007,
2359 UT.
