From: Antonio Costa <antonio.costa@xxxxxxx>IUGG 2015. Session VS17: Dynamics of Eruption Clouds
****************************************************************************************************
Dear Colleagues,
We would like to draw your attention to the IUGG 2015 Session VS17:
Dynamics of Eruption Clouds
at the 2015 IUGG General Assembly in Prague (22nd June - 2nd July).
During such a session results of the IAVCEI volcanic column model inter-comparison exercise will be also presented.
Convener: Antonio Costa (INGV, Italy)
Co-conveners: Yujiro Suzuki (Earthquake Research Institute, The University of Tokyo, Japan)
Description
The accurate description of the dynamics of convective columns developed during
explosive volcanic eruptions represents one of the most intriguing and crucial challenges
in volcanology. Eruption column dynamics are significantly affected by the complex
interactions of the volcanic plume and the atmospheric wind field, during both strong
eruption columns, rising above the tropopause, and weak volcanic plumes, developing within
the troposphere and following bent-over trajectories. The understanding of eruption column
dynamics is pivotal for estimating volcanic source mass flow rate. Estimation of such mass
flow rate is also crucial for tephra dispersion models used to assess aviation safety and
population hazards. Papers that quantify such processes combining theoretical studies,
observations and laboratory experiments are particularly welcome.
Yours sincerely,
Antonio & Yujiro
