Fall AGU Session: Tephra Dispersal and Sedimentation
******************************************************
From: Christopher F. Waythomas <chris@xxxxxxxx>
We would like to solicit your participation in the following session at
the Fall 2006 AGU meeting:
Session V16: Tephra Dispersal and Sedimentation: Field Studies, Modeling,
and Hazard Assessment
This special session will bring together scientists with active research
interests and expertise in the application of tephra studies to developing
numerical models of tephra dispersion and sedimentation. Tephra produced
by volcanic eruptions poses a substantial risk to the aviation industry
and tephra fall out represents a significant public health and societal
hazard. Accurate forecasts of particle dispersal and fall out are critical
during volcanic crises and are important components of volcano hazard
assessments where both short- and long-term volcanic risk must be
estimated. The session will highlight recent work on the analysis of
tephra hazards and the integration of field studies and numerical modeling
of particle transport and fall out. The session will also address topics
such as: (1) strengths and weaknesses of existing numerical models for
tephra transport and sedimentation, (2) tephra databases for model
validation, calibration and development, (3) new techniques for collection
and monitoring of tephra during eruptions, (4) critical assessments of
existing techniques for the study of tephra deposits, (5) long-distance
transport of volcanic ash and methods for hazard assessment at large
distances from source volcanoes, (6) environmental and societal impacts of
tephra fallout, (7) risk mitigation, (8) communication of tephra hazards
and warnings with the public and other physical scientists, (9) future
collaborative opportunities and needs.
The Abstract deadline is September 7, 2006.
