National Strong-Motion Program Data Sets

The US Geological Survey National Strong-Motion Program (NSMP) Data Sets Web site contains three informative and helpful digital data compilations. These include the Digitized Strong-Motion Accelerograms of North and Central American Earthquakes 1933-1986, which is a collection of 1,477 three-component station recordings from nearly 500 earthquakes. The second is the National Strong-Motion Network (NSMN) Accelerograms data set that has time series data recorded by NSMN stations for selected earthquakes since 1989. Lastly, there is the General Earthquake Observation System (GEOS) Accelerograms, which has recordings collected by the NSMP GEOS project for aftershock studies, long-term deployments, and short-term experiments. Each can easily be accessed via the main site and contain updated information from as recently as an April 22, 2003 California event.
