Cyber technology has reached a stage where the time is right for developing new open mechanism on the internet for dissemination of ideas, data, and models regarding geologic hazards and volcano-related situations in particular. We would like to propose a forum for discussing various web-based frameworks for promoting better communication and information transfer among researchers and others with a common interest in various sets of geophysical mass flow models. This session would highlight presentations on existing HUB structures and recommend guidelines that would be useful for developing additional web-based structures for improving and dissemination conversations among geoscientists regarding models, data, and applications. This session will not deal with models, per se, but rather with the development of communication systems among scientist and others who use and test models.
