Thank you for requesting to download strong-motion data from the Center for Engineering Strong Motion Data. Please choose one of the following:
Processed Data
Acceleration, velocity, displacement and spectra files, as processed and reviewed by CGS/CSMIP or USGS/NSMP (the traditional Vol2 and Vol3 files, used for most applications).
Raw Data
The corresponding raw, unprocessed acceleration data, with no noise filtering, no baseline or sensor offset corrections, etc. (the traditional Vol1 file, used for specialized research studies).
