Dear colleagues,
We would like to draw your attention and invite submissions to the session
GMPV7 - Volcanic ash: an agent in Earth systems at the EGU General Assembly
2010 (2 – 7 May) in Vienna, Austria.
Description:
Volcanic eruptions are an unavoidable natural hazard and their impact can be
local, regional as well as global depending on the eruptive style. Ash
particles are a common product of volcanic eruptions. Upon transport and
deposition, ash poses a range of hazards to human and animal health,
infrastructures (e.g., power blackout, building collapse), air traffic, and
agriculture over variable time scales. Understanding the generation of ash
is vital to hazard assessment.
Ash is a descriptive and non-genetic term. Ash refers to a grain size of
particles (< 2 mm) that can be generated by primary processes such as
1) bubble burst due to gas expansion,
2) magma rupture at high shear rates,
3) abrasion from friction and collision,
4) magma-water interaction,
5) crystal disintegration,
and modified during transport. Such processes concur in determining the role
of volcanic ash as an important agent in Earth systems. We propose an
interdisciplinary session on physical and chemical aspects of ash genesis
and modification that aims to fill the current gap between volcanological
and environmental studies.
