CSMIP Station Information

The California Strong Motion Instrumentation Program (CSMIP) in the Department of Conservation's California Geological Survey was established in 1972 to obtain vital earthquake data for the engineering and scientific communities through a statewide network of strong motion instruments. CSMIP is funded by a portion of local government building permit fees, with additional funding from other State and Federal agencies. The information gathered by CSMIP is processed and disseminated to seismologists, engineers, building officials, local governments and emergency response personnel throughout the state. The data is used to develop recommended changes to seismic provisions of building codes, to assist local governments in their general plan process and to aid emergency response personnel in the event of a disaster. When the planned network is completed, statewide coverage will ensure that strong ground motion for any moderate to larger size earthquake in the state will be recorded.

CSMIP installs state-of-the-art earthquake monitoring devices called "accelerographs" at various representative geologic foundation materials throughout California to measure the ground shaking. In addition, earthquake monitoring devices are installed in structures such as buildings, hospitals, bridges, dams, utilities and industrial facilities. Sites are selected by engineers and scientists representing industry, government, and universities. The program has installed more than 900 stations, including 650 ground-response stations, 170 buildings, 20 dams and 60 bridges.
