*****************************************************************************************************
Colleagues,
We'd like to announce the
following session on volcanic emissions at the 2016 EGU Meeting in
Vienna (17-22 April 2016). This session will form part of a new
'Interdisciplinary Event' at EGU (IE2 Volcano Emissions) in which
several related sessions will be linked and scheduled consecutively in
the same room. Note that the abstract deadline (13 Jan 2016) is soon
after the impending holiday season, so please plan ahead.

Session description:
Emissions
from volcanoes can pose a major hazard both near to the volcano and in
the far field. Volcanic ash has a melting point close to the operating
temperature of many aircraft engines and so can cause engine failure, in
addition to sandblasting and visibility problems. The 2010 eruption of
Eyjafjallajokull demonstrated the huge economic cost that can follow
from airspace closure, and the widespread disruption to freight-related
services worldwide, highlighting how critical it is to have the
knowledge to constrain the hazard in space in time. Airborne ash and SO2
are also known to cause respiratory problems for both humans
and livestock, even when in relatively low concentrations. Effective
monitoring is required in order to issue timely warnings to those
potentially affected. Closer to the volcano, dense ashfall can smother
crops, leaving land unproductive for a long time afterwards, and in some
cases can cause structural collapse of buildings, thereby endangering
life and infrastructure. Further to these incentives for accurate
observation and monitoring, interpretation of emissions can yield useful
information about the volcano itself and provide an aid to predicting
the evolution of an eruption, and to understanding volcanic processes.
Volcanic emissions can consist of a broad range of materials, with a correspondingly broad range of properties. This creates many challenges for their observation, both close to the source, where a wide variety of instruments can be used (logistics allowing), and in the far-field, where ground- and air-based observations (when available) can be combined with satellite observations. Using such observations to constrain and inform forecast models for timely warning of potential hazards is a challenging area of ongoing research.
We invite abstracts presenting novel techniques for observing volcanic emissions from ground-, air- and space-based instruments, and for the use of such observations in dispersion modelling. Abstracts describing the effective validation of both new and existing methods for the observation and forecasting of volcanic emissions are also invited – we are interested in both comparisons between different methods, and in uncertainty assessments for specific methods.
