The SCEC Community Stress model (CSM) was developed to assemble contributed observations and geodynamic models of stress and stressing rate, as one of the SCEC Community Models (CXM) designed to improve understanding of seismic phenomena in California. There are currently eleven models of stress and stressing rate available for community use, representing the cumulative progress of the CSM throughout SCEC4 and SCEC5. A significant success of SCEC5 has been the improvement in access to CXMs. Here we report on progress on the CSM through improvements to the homepage, public access to the complete model (archived with a DOI), and a web-based tool to visualize and query the various CSM models.... We invite all persons to test out the CSM visualization tool, to explore and compare different models.

The SCEC CSM Viewer allows users to explore the contributed models at different depths and using different stress metrics. It builds on existing CXM tools that do not need specialized software installed (e.g., the CFM web tools). Users can now quickly visualize and then download model stress orientation (SHmax or Aphi) and magnitude (isotropic or differential stress) data from a specified region and depth of interest. Users can overlay the CFM fault traces, as well as the regions of the Geologic Framework Model (from the SCEC Community Rheology Model). Going beyond comparisons with other CXM products, users can also upload their own data (in .kml or .kmz format) for visualization against the SCEC CSM. The CSM Viewer allows any user to quickly browse the CSM and to determine the model most appropriate for their use.

Significant updates have been made to the CSM homepage to facilitate broader understanding and usage of the SCEC CSM products. We created an official and citable CSM archive with a DOI, where all existing CSM model contributions and metadata are permanently stored at Zenodo. The CSM archive contains individual model files that have been updated to a more user-friendly comma-separated value (.csv) format, and are documented with complete model metadata (.pdf format) collected from contributors. The CSM homepage has been streamlined to concisely describe the CSM and each of its contributed models, and updated to link to these new model resources and facilitate new contributions of stress models and observations.
