Strong-motion records were recovered from 193 CSMIP stations following the Northridge earthquake. The accelerograms, information on the earthquake and recording stations are presented in the CSMIP data report on this earthquake (Shakal and others, 1994). The results of digitizing and processing for the first release of 5 records were announced on February 4, 1994 and were included in the first release report (Darragh and others, 1994a). The results of digitizing and processing for the second release of 5 records were announced on February 24, 1994 and were included in the second release report (Darragh and others, 1994b) . The results of digitizing and processing for the second release of 7 records were announced on March 15, 1994 and were included in the third release report (Darragh and others, 1994c). Details on accelerogram digitizing and processing will be presented in a forthcoming final CSMIP processed data report.
