CoV9. call for conference abstracts - Session S2.2 Re-suspended Volcanic Ash: Forecasting, Modelling, Observations and Hazards
*****************************************************************************************************
Dear all,
We would like to draw your attention to the following session at Cities
on Volcanoes 9, to be held in Puerto Varas, Chile during the 20th – 25th November 2016.
S2.2 Re-suspended Volcanic Ash: Forecasting, Modelling, Observations and Hazards
Conveners: Frances Beckett (Met Office, UK), Kathy Cashman (University
of Bristol, UK), Emma Liu (University of Bristol, UK), Arnau Folch
(Barcelona Supercomputing Centre), Soledad Osores (CONICET, CONAE, SMN)
and Paula Acethorp (VAAC Wellington).
Invited Speaker: Tom Wilson (University of Canterbury, New Zealand)
Session description:
Volcanic ash can continue to pose a hazard
long after an eruption has ended. Ash deposits can be remobilized under
favourable meteorological conditions in
the months and years following an eruption to form re-suspended ash clouds which can be transported tens to thousands of kilometres. Most recently significant ash re-suspension events have occurred following the eruptions of Eyjafjallajökull in 2010 and Grímsvötn in 2011 (Iceland), and Puyehue-Cordon Caulle in 2011 (Chile). Re-suspended ash clouds can pose significant hazards to the local population, decreased visibility levels impact ground transportation and airports and the associated poor air quality can be a concern for humans and livestock. To forecast the re-suspension and subsequent transport of volcanic ash, remobilization schemes are being used in conjunction with ash dispersion models. This is a challenging area of research which requires an understanding of the emission of particles from the surface, the changing source areas, the physical characteristics of the particles and the local meteorological conditions. Validation of the forecasts requires both ground and space-based observations and identifying re-suspended ash clouds in observation data is also challenging. We invite abstracts presenting novel techniques for modelling, observing and forecasting the re-suspension and subsequent advection of volcanic ash. We would like to hear about the development and calibration of emission schemes, the assessment of source areas, the use of observations, and their application in producing operational forecasts. We also invite abstracts which consider the hazards posed by re-suspended ash clouds.
Please note that the abstract deadline is the 15th July 2016.
