Description

Tens of millions of people around the world are at risk from volcanic eruptions. The risk is increasing rapidly as populations grow in active volcanic regions, and as national economies become increasingly intertwined. In addition to their significance to risk, volcanic eruption processes form a class of multiphase fluid dynamics with rich physics on many scales. Risk significance, physics complexity, and the coupling of models to complex, dynamic spatial datasets, demand the development of advanced computational techniques and interdisciplinary approaches to understand and forecast eruption dynamics. Innovative cyberinfrastructure is needed to enable global collaboration and creative new science, while simultaneously enabling computational thinking in real-world risk mitigation decisions . an environment where quality control, documentation, and traceability are key. The goal of this session is to discuss needs and solutions that can be addressed through a global collaborative online environment such as the recently initiated VHub effort (see "http://geohazards.buffalo.edu/VHub/"), GEO Grid, and others. In particular, we are interested in presentations and discussions around, but not limited to, the following themes: • Dissemination. Make advanced modeling and simulation capabilities and key data sets readily available to researchers, students, and practitioners around the world. • Collaboration. Provide a mechanism for participants not only to be users but also co-developers of modeling capabilities and validation/verification/benchmarking methods, and contributors of experimental and observational data sets for use in modeling and simulation, in a collaborative environment that reaches far beyond local work groups. • Comparison. Facilitate comparison between different models in order to provide the practitioners with guidance for choosing the "right" model, depending upon the intended use, and provide a platform for multi-model analysis of specific problems and incorporation into probabilistic assessments. • Application. Greatly accelerate access and application of a wide range of modeling tools and related data sets to agencies around the world that are charged with hazard planning, mitigation, and response. • Education. Provide resources that will promote the training of the next generation of volcanologists and hazards specialists such that modeling and simulation form part of a tripartite foundation of approaches, alongside observational data and experimentation.
