The U.S. Geological Survey (USGS) and the California Geological Survey (CGS) have established a cooperative U.S. National Center for Engineering Strong Motion Data (NCESMD), which will have mirrored operational centers in Sacramento and Menlo Park, CA. The National Center integrates earthquake strong-motion data from the CGS California Strong Motion Instrumentation Program, the USGS National Strong Motion Project, and the regional networks of the USGS Advanced National Seismic System (ANSS), thus serving as a provider of uniformly processed strong-motion data for seismic engineering applications. The NCESMD builds on the Engineering Data Center of the California Integrated Seismic Network, and so will continue to serve the California region while expanding to serve other ANSS regions. The National Center will assimilate the Virtual Data Center, which was developed at U.C. Santa Barbara with support from the Consortium of Strong Motion Observation System (COSMOS), NSF and SCEC. A Center Management Group with input from an external Advisory Committee manages the NCESMD. Products will be generated by both CGS and USGS facilities, thus ensuring robustness. Each ANSS region is responsible and credited for the data recorded by its regional network. The National Center is co-hosted by CGS and USGS at
