The California Department of Conservation, Division of Mines and Geology has been involved in the development of data on the characteristics of earthquake-generated strong motions for ten years. The statute that brought the Division's Strong Motion Instrumentation Program (SMIP) into being on January 1, 1972, gave it the role of procuring and installing strong-motion instruments in representative structures and geologic environments in the state; the statute left instrument maintenance, record collection, and record processing to be accomplished through agreement with other agencies. A subsequent statute, which became effective on January 1, 1977, expanded the program's mandate to include instrument maintenance and record processing. The Division of Mines and Geology, anticipating this expansion, began collecting and archiving records from its own instruments in September 1976.

This catalog consists of entries for SMIP strong-motion records recovered from that time through to the end of 1981. These entries present information about the available records; the records themselves are not presented. The catalog will be updated as new records are recovered, and new entries will be sent periodically to those who have the catalog and who request the updates.

The catalog incorporates recommendations and comments by the management of the California Division of Mines and Geology, the staff of the Strong Motion Instrumentation Program, and the members of the Strong Motion Instrumentation Committee, Seismic Safety Commission. All suggestions from the users of this catalog will be appreciated. Such suggestions, as well as orders for this catalog or any inquiries, should be directed to:
