AB: Some recent research at UNAVCO and the University of Colorado has been focused on Rocky Mountain tectonics, and Information Technology (IT) in the areas of data visualization and distributed data serving. At UNAVCO, we are participating in the geodynamics work in the Rocky Mountain Testbed of the GEON NSF funded (IT) Research project (www.geongrid.org). As part of this work, a variety of seismic tomography models, GPS velocity vector data, strain rate models and other data have been recompiled into a standard format. These data and models are being incorporated into our OPeNDAP server and the Integrated Data Viewer (IDV). OPeNDAP servers are platform independent, self-describing distributed data servers allowing easy access to a wide audience. The IDV is a freely distributed visualization and analysis tool developed by UCAR that has several exciting capabilities such as online collaboration, and a variety of 1-d, 2-d and 3-d viewing options. Necessary solid earth viewing capabilities (earthquakes, focal mechanisms, faults, etc.) are currently being added to the IDV. Both our OPeNDAP server and visualization tool are being integrated into the GEON portal, a website for data searching, analysis, and visualization. Designing and implementing such systems now allows us to be more prepared for the volumes of data anticipated from various EarthScope projects. As part of the scientific research for GEON, we have also begun investigations of Colorado seismicity. The 1992 Rocky Mountain Front IRIS/PASSCAL seismic experiment recorded many local earthquakes. We have begun to locate these events and are working to create focal mechanisms and calculations of stress drop for this region. These will aid in improving seismic hazard and risk assessments for the rapidly growing Rocky Mountain population. New IT capabilities will help augment the quality of this work through sharing the data with a larger audience, providing a means to view and analyze integrated data, and quickly providing a computationally intensive baseline by which results can be checked.
