abstract: The Strong Motion Earthquake Data Values of Digitized Strong-Motion Accelerograms is a database of over 15,000 digitized and processed accelerograph records from 1933 to 1994. Data were obtained from a variety of structural and geologic environments. Most of the data are available in three levels of processed files. The first type of file contains raw (uncorrected) time, history data points digitized from the analog accelerogram. The second is a filtered, instrument corrected version of the time, history data. This file also contains calculated velocities and displacements obtained by the integration and double integration of the corrected accelerations. The third type of file includes the calculated Fourier and response spectra data. The data are from the United States, Algeria, Argentina, Armenia, Australia, Bulgaria, Canada, Chile, China, El Salvador, Fiji, Germany, Greece, India, Iran, Italy, Japan, Mexico, New Zealand, Nicaragua, Papua New Guinea, Peru, Portugal, Romania, Spain, Taiwan, Turkey, and Uzbekistan. This database is static and is no longer being updated.
purpose: Provide strong motion earthquake data for engineering research

aName: Uncorrected Acceleration
attributeType: (unknown)
descriptor: The peak uncorrected or raw acceleration value in cm/sec2. The term "uncorrected" indicates that a digitized or digitally recorded time series has received no processing that involves any hypotheses as to the character or frequency content of the ground motions or recording instruments. An "uncorrected" analog-recorded time series has been corrected only for uneven film transport with time, for transverse motion of the film as it moved longitudinally through the recorder, and for angular tilts between the baselines of adjacent scan segments of long records. Time series derived from both analog and digitally recorded data have been shifted to have zero mean; and have been converted from digitization units or volts to units of cm/sec/sec (ordinates) and seconds (abscissas).

descriptor: All of the digitized strong motion data are arranged into sets grouped by either triggering events or geographic regions. These sets are identified by a particular data set number (such as SM-USACA01 or SM-TAI04). Most of the data sets include three types of processed records: uncorrected (raw), corrected (filtered), and response spectra (includes Fourier spectra). Each data set is distributed with documentation containing (when available) information on the triggering earthquakes, recording stations, record processing procedures, and data format. These data were originally available on a three-volume CD collection. The contents of each volume are available for download. The UNC TAPE column indicates the directory the dataset of interest is located. The datasets are listed in the /data directory and the files are located in the /records directory under the dataset directory. The UNC FILE column indicates the file number for a particular record.
