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.
Measurements of changes in the distance (or length) between monuments are provided. These measurements were made using a two-color Electronic Distance Meter (EDM) that can measure distances between 1 and 10 KM. Nominal precision of these data range from 0.3 mm to 1.0 mm dependent upon the baseline’s length. These measurements were made between mid-1975 to mid-2006. Data in this archive are from eight networks, each consisting of more the 9 baselines. The locations of these networks in California include far northwestern California, Hollister, CA., Long Valley Caldera in eastern California, Parkfield, Pearblossom, and Anza; the last two located in Southern California. For four of the networks (Hollister, Parkfield,...
