Abstract: Three datasets were analyzed and maps were prepared of near-source ground motions associated with the Whittier, Northridge, and Landers earthquakes in southern California. Vertical motions were enhanced in the near-source area of high-angle thrust faults at Whittier and Landers, similar to Northridge. Factors are provided for the enhancement in terms of site conditions. Distance factors were established with vertical-to-horizontal ratios. Areal patterns of earthquake ground motions were plotted with relation to known faults.
