The data from the borehole strainmeter network set consists of raw data from the telemetry, state of health measurements, environmental measurement of temperature and pressure, and processed borehole strainmeter data. For each strainmeter site in this network, there will be a mix of raw data, SOH, environmental data, and processed strain. Each channel of data consists of a time of observation, usually 10-minute intervals, and a number that is either telemetry counts (which is proportional to the voltage output by the instrument), or in units of strain, which are either in part per million or parts per billion. Processed strain will be free of glitches and other artifacts and are corrected for changes in atmospheric...

These data provide measures of aseismic slip (creep) at approximately 40 sites located on the San Andreas, Hayward, and Calaveras faults in Central California from Point Pinole located in the San Francisco Bay area to south of Parkfield, California. The earliest measurement of creep followed the 1966 Parkfield earthquake. Currently, we maintain approximately 20 creepmeters and those data are uploaded to the web daily. The data provided at http://earthquake.usgs.gov/monitoring/deformation/data/download/table.php include measurements for sites that have been abandoned. The table provides the location of each creepmeter, and where present, notes that might be relevant to interpreting the data from each instrument.
