National Strong Motion Project (NSMP)

Description / purpose

The USGS National Strong-Motion Project (formerly titled the National Strong Motion Program) has the primary Federal responsibility for acquiring strong motion records of significant earthquakes in the United States recorded by sensors placed in the ground and in man-made structures. Currently the NSMP operates and maintains strong-motion instruments at more than 660 ground, free-field and reference sites, and more than 3200 channels of data from about 180 structural arrays. When a significant earthquake occurs, the NSMP automatically retrieves strong motion recordings from its instrumentation as well as from more than 2000 other instruments operated throughout the US by federal, state, and local agencies, private companies, and academic institutions that participate in the Advanced National Seismic System (ANSS). The NSMP rapidly processes these recordings according to COSMOS standards and archives the products at the Center for Engineering Strong Motion Data.
