Abstract:
We report here on an effort to improve the sustainability, robustness and usability of the core modeling and simulation tools housed in the collaboratory VHub.org and used in the study of complex volcanic behavior.

In particular, we focus on tools that support large scale mass flows (TITAN2D), ash deposition/transport and dispersal (Tephra2 and PUFF), and lava flows (Lava2). These tools have become very popular in the community especially due to the availability of an online usage modality. The redevelopment of the tools ot take advantage of new hardware and software advances was a primary thrust for the effort. However, as we start work we have reoriented the effort to also take advantage of significant new opportunities for supporting the complex workflows and use of distributed data resources that will enable effective and efficient hazard analysis.
