Field observations on overturning of tombstones during the Hyogo-ken Nanbu Earthquake was performed in and around Kobe City. The relation of geomorphological condition and geomorphometric measures (elevation and gradient) with the overturning rate of tombstones was examined quantitatively, and the empirical equations between the gradient and the overturning rate were proposed for each geomorphological condition. The distribution of the overturning rate in the disastrous area was estimated by the equations together with the geomorphological map. The distribution of the overturning rate was transformed into the distribution of peak ground velocity by using the relation derived from the observed peak ground velocity and the overturning rate of tombstones.
