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 www.strongmotioncenter.org

• 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:

www.strongmotioncenter.org

• Each ANSS region is responsible for and credited for the data recorded by its regional network.
