Brune (1996, 1999) proposed using balanced rocks located at a variety of distances from faults, some with relatively high slip rates (e.g., the San Andreas fault), as proxy paleo-ground-motion indicators of peak acceleration. Shi et al. (1996) derived simplified relationships between peak horizontal accelerations (PHA) and toppling probabilities to convert pseudostatic field measurements of rock pedestal stability to limits on PHA consistent with rock stability and persistence. Anderson and Brune (1999) concluded that the persistence of balanced rocks 10-30 km from the San Andreas fault was inconsistent with the ergodic assumption...
