This list of current structural arrays is grouped into five broad categories based on the “Station Type codes” defined in Table 6 of the COSMOS1 data format:

Densely instrumented structures, such as in Los Angeles and in San Francisco, may have 36 or more sensors.

“Site Agency” designations other than “U.S. Geological Survey” generally denote that these agencies purchased the equipment and/or partner with the NSMP in the operation and maintenance of the equipment. Supporting metadata that describes the “SEED” (Standard for Earthquake Data Exchange) instrument response for each data channel is available at the Northern California Earthquake Data Center. The International Federation of Digital Seismograph Networks code for all NSMP stations is “NP”.

All NSMP waveform products are publicly available for download at the Center for Engineering Strong Motion Data.
