U.S. NATIONAL CENTER FOR ENGINEERING STRONG MOTION DATA (NCESMD) Hamid Haddadi, Anthony Shakal and Moh Huang California Geological Survey and Woody Savage and Chris Stephens US Geological Survey
National Center for Engineering Strong Motion Data Goal: Provide timely, quality-controlled, and easily accessible data for domestic and foreign earthquakes of engineering interest Single unified facility includes functions of receiving data from field stations, processing data, rapidly releasing data via the web site, and archiving data
NCESMD a cooperative center … Built on the Engineering Data Center of the California Integrated Seismic Network (CISN) Will continue to serve the California region while expanding to serve the other ANSS regions of USGS Established by the USGS and CGS to integrate strong ground motion record access
NCESMD Web Site Web site is dynamic - all web pages are generated on- the-fly, upon user need/request Data and information are retrieved from a database in real time when users open web pages At Provides basic station information type of station (ground response or structure) photo showing station setting site conditions (surface geology, Vs30) list of records obtained

SUMMARY NCESMD: A unified strong-motion data center for engineering applications A Center Management Group manages the NCESMD with input from an external Advisory Committee Products will be generated by both CGS and USGS facilities. Incorporate the COSMOS VDC – transition is just beginning Database-driven site with dynamic pages and a new map feature that facilitate the use of strong-motion data Co-hosted by CGS and USGS at: Each ANSS region is responsible for and credited for the data recorded by its regional network.
