Abstract

Eight trilateration networks located along the San Andreas fault in southern California have been surveyed 8 to 19 times within a 14- to 17-year interval between 1971 and 1992. The hypothesis that the interseismic deformation is steady is tested by examining whether deviations from linear fits to the data in the plots are within the range expected for observational error. A significant deviation from steady deformation is found only for the network located near Palmdale, California. In that network, many of the measurements made in the survey of early 1982 deviate from the trend defined by the measurements in other surveys. If the survey of early 1982 is excluded, the remaining data at Palmdale are consistent with steady deformation. Thus the apparent strain event observed near Palmdale in 1982 was transient. -from Authors
