Probabilistic hazard risk estimates using Bayesian uncertainty quantification need ensemble methods to explore the parameter space, requiring complex sequences, interactions and exchanges of data and run-time determined computations. In order to make this analysis easier for end researchers to access, a portal based access to the toolkit has been developed.
The portal accessible via Volcano Hub makes it accessible to a large number of geologists all over the world. Using this portal, geologists can execute workflows for hazards from volcanic debris avalanches and atmospheric ash transport. The Pegasus Workflow Management System (WMS) in conjunction with HTCondor on the HUBzero.org’s VHUB site, provides the structured platform required for implementing these workflows.
