Peak accelerations recorded near the causative faults of recent large earthquakes have been smaller than expected from published attenuation relations (Somerville, 2000; Anderson et al., 2000). This discrepancy provides a motivation to find new empirical fits of peak ground motion to functional forms that account for the extended nature of the source at locations near the fault (Ohno et al., 1993; Ambraseys and Srbulov, 1998). It has long been proposed (Housner, 1965; Brune, 1970; Hanks and Johnson, 1976) that peak acceleration and short-period velocity spectral response approach constant values at...
