Dear Colleagues,
We would like to draw your attention to session 1.II.A: “Pyroclastic Currents: Linking Field Observations, Laboratory Experiments and Numerical Modeling for Hazard Assessment and Mitigation” for abstract submission at the Cities on Volcanoes 8 meeting in Yogyakarta, Indonesia (Sept 9-13, 2014).
Conveners: Sylvain Charbonnier (USF, USA) Eliza Calder (University of Edinburgh, Scotland), Jean-Christophe Komorowski (IPGP, France), Roberto Sulpizio (INGV Pisa, Italy), Tomaso Esposti Ongaro (INGV Pisa, Italy), Susanna Jenkins (Bristol University, England), Karim Kelfoun (LMV, France)
Session description:
Pyroclastic density currents (PDCs) are hot particles and gas mixtures that flow across the ground; they are initiated by different sources and triggers during explosive eruptions or gravity-driven collapses of lava domes. Interest in the hazards associated with the emplacement of PDCs is justified by both the complex physics they involve and by their dangerous nature. Traditional field-based techniques for studying PDCs are crucial to both improve our knowledge of their transport and deposition processes and collect datasets of the sources, extents, lateral variations and impacts of PDC deposits. Moreover, recent progress with analogue, analytical and numerical models has offered noteworthy insights into the fundamental dynamics of PDCs. The integration of results and constraints from field-derived data, laboratory experiments and numerical modeling is one of the main challenges for future research into the dynamics of PDCs. A combination of these different techniques is vit
al for an accurate characterization of areas prone to such flows and their associated hazard levels, thereby reducing their future impact and risk. We invite contributions from all those involved in field-based, experimental, theoretical, numerical and related hazard studies of PDCs. This session aims to draw together various contributions in order to highlight new approaches, methodologies and results. It also aims to discuss how to test objectively the models and how to use them, in concrete terms, in the event of an eruptive crisis.
The abstract submission deadline is Monday, April 14, 2014. Full details can be found on http://www.citiesonvolcanoes8.com.
Hope to see you all in Yogya!
