Description:

The service provides transnational access to a workflow (Ch-PVHA) to perform long- and short-term probabilistic volcanic hazard assessment (PVHA) for tephra fallout at ground and ash concentration at flight levels for a specific volcano, possibly at high resolution (2km x 2km) and on large-scale domain (2000 km x 2000 km).

The Ch-PVHA workflow updates Bet-Tephra Python software package, and is based on the Bayesian Event Tree methodology. It uses the WMS-light and interacts with the ash dispersion model FALL3D to simulate a large number of possible eruption scenarios and perform PVHA.

The service will be provided through trans-national access (TA), including training, co-design of the experiment, computational resources, and assistance for all phases during a physical stay. The TA will take place at INGV-BO and CSIC, and will include (i) remote and on-site training to the FALL3D model (with CSIC) and to the Ch-PVHA workflow (with INGV-BO), and (ii) access to such workflow to perform long- and short-term probabilistic volcanic hazard assessment for tephra fallout at ground and ash concentration at flight levels for a specific volcano, at high resolution and on large-scale domain.

Target community/Users: Researchers, Students, Hazard Practitioners
