Flexure in the Corinth rift: reconciling marine terraces, rivers, offshore data and fault modeling
Résumé
The Corinth rift (Greece) is an exceptional area to study the large-scale mechanics of a young rift system due to its extremely high extension rates and fault slip rates. Middle-Late Pleistocene activity of large normal faults has created a mostly asymmetric E-W trending rift, mainly driven by N-dipping faults that shape the southern margin of the Corinth Gulf in an en echelon pattern. We improve the onshore record of footwall uplift by analysing the most extensive sequence of marine terraces in the SE margin, combine this dataset with the offshore seismic record of hanging wall subsidence, and present simple numerical models to fit the observations.
