Workshop Overview


The first of our RCN's three workshops focused on assessing the critical aspects of fluid transport that should be included in the future integrative community modeling framework for subduction zones. We brought together a diverse selection of modelers and earthquake and volcano scientists to synthesize existing modeling efforts and identify the disconnects and knowledge gaps between fluid migration models of various spatial and temporal scales. This workshop was designed to facilitate discussions on and collaborations toward developing the modeling framework on fluid migration, but was not designed to develop modeling codes.

  • Identify the key processes at different temporal and spatial scales that are critical to fluid migration.

  • Identify the disconnects among models of different scales and/or mechanisms and the knowledge gaps among modelers.

  • Synthesize and direct existing efforts towards building a framework for fluid migration modeling for earthquake and volcano systems.

  • Build a community plan for an integrative fluid migration modeling framework for earthquake and volcano systems.
