Uplifted Pleistocene and Holocene marine and fluvial deposits are preserved in the footwall of the Eliki fault, western Gulf of the Corinth, where geodetic extension rates exceed 10 mm a −1 . Up to 10 Pleistocene terraces are distinguished in the footwall block of the eastern Eliki fault segment, discontinuously preserved along strike. Terraces are depositional, forming by the progradation of clastic fan deltas, or predominantly erosional, between fan deltas. Correlation of terrace profiles with Late Pleistocene eustatic sea level suggests an uplift rate of c . 1 mm a −1 , with an alternative of c . 1.5 mm a −1 . On average, higher rates are obtained from uplifted Holocene deposits ( c . 1–2 mm a −1 ). To determine slip rates, a long-term ratio of uplift to subsidence of c . 1:2–3.2, derived from net footwall altitude and basin subsidence–fill and a fault dip of 50° are applied to uplift of c . 1 mm a −1 . These produce a slip rate of c . 4–7 mm a −1 contributing c . 2–4 mm a −1 to extension across the Gulf, significantly less than geodetic rates. This discrepancy may result from strain taken up on faults to the north and offshore. Uplift rates decrease little at the Eliki fault tips. Uplift rates are broadly consistent in the central–western Gulf but show a decrease in average uplift from Corinth eastward.

Along the southern coast of the Gulf of Corinth, important coastal uplift is illustrated by raised Late-Pleistocene marine platforms. Terrace remnants preserved on the footwall of the Aigion and Eliki Faults were mapped in detail. To derive cumulative uplift rates, the individual terraces were tentatively correlated with the eustatic sea-level curve, constrained by some direct dating of the deposits blanketing the terraces. We obtain uplift rates of 1.05-1.2 mm yr −1 for the Aigion Fault footwall and of 1.0 and 1.25 mm yr −1 for the East and West Eliki Fault footwalls respectively. A forward modelling procedure was adopted to fit the best-preserved terrace transects, using a code based on standard dislocation theory and assuming reasonable scenarios of regional uplift. We obtained maximum slip rates consistently in the range of 7-11 mm yr −1 for the West and East Eliki Faults and of 9-11 mm yr −1 for the Aigion Fault.
