Abstract : The research training activities started by identifying and picking seismic events from various broadband arrays and networks. The next step was to associate these events with existing catalog locations to build databases of local, regional and teleseismic events which are being used in this research project as well as other seismic verification projects at our institute and also other universities. The data processing aspects included learning to use the CSS 3.0 database format to allow the management of datasets with thousands of events. The seismic processing included identification of local, regional, and teleseismic phases which are essential for seismic discrimination research. This involved learning the TCLITK language and the application of this knowledge to provide a graphical user interface to build CSS databases. This program is being developed to support field deployments of seismic stations which will ensure the proper documentation of instrument responses, site locations, and calibration parameters. In addition, this software has been used to support deployments of the Wyoming portable broadband seismic and infrasonic experiments, and with all aspects of data assembly, data processing, data distribution to the research community.
