Abstract

An understanding of fault kinematics in areas of active tectonic deformation requires detailed knowledge of local and regional ground-surface displacement vectors. Where faulting displaces coastlines, dated raised marine notches can provide reference markers to measure the magnitude, rate and timing of fault displacement [Pirazzoli, 2005]. This is particularly important in areas of multi-generational faulting and where uplift may include both local and regional scale components, features which characterise the actively extending Gulf of Corinth rift (Figure 1). Cooper et al. [2007] interpret the distribution and elevation of raised Holocene and marine isotope stage (MIS) 5 (∼125 ka) fossil shorelines from the Perachora peninsula in the Gulf of Corinth as due to spatially variable uplift along the fault footwall of a western segment to the Pisia fault which ruptured in 1981 [Jackson et al., 1982]. This comment draws attention to previously published studies of raised shorelines in the area and presents new field observations that help test the structural uplift models of Cooper et al. [2007] and Morewood and Roberts [1999].
