g>Events in the Watsonville earthquake sequence of August and September 1963 were found by Udias (1965) not to concentrate on the main San Andreas fault break. New locations are found using a more site-specific velocity model with carefully determined station adjustments. Resulting relocated hypocenters indicate that this sequence probably does not exhibit the anomalous spatial scatter found previously. The revised locations are found to be consistent with patterns of recent seismicity, based on dense network coverage, which show a tight coincidence with the San Andreas fault.g>
