Abstract
While morphometric analysis of young normal fault scarps in Quaternary colluvium and alluvium is a powerful tool for assessing the timing of earthquake activity in a number of active tectonic terrains, normal fault scarps in the Aegean region are commonly developed in limestone bedrocks. These "Aegean-type scarps' are underlain by a layered architecture of fault rocks of contrasting resistance to erosion that give rise to a temporally and spatially variable pattern of degradation. A more fruitful approach to the palaeoseismological dating of "Aegean-type' fault scarps is suggested to involve the detailed analysis of the karstification of their surfaces. The recognition that "ram-type' and "step-type' morphologies, end members of a continuum of range-front forms, are independent of the rate and duration of geomorphological activity, necessitate cautious applications of purely geomorphic indices to identify contrasting degrees of tectonism along different range forms. -from Author
