Translated title:
Morphotectonic study of the central southern margin of the Gulf of Corinth
This report is a primary stage study of the main morphotectonic features on the
southern margin of the central part of the Gulf of Corinth. Features that could connect
the most thoroughly studied eastern (Corinth – Xylokastro) and western (Akrata – Rio)
parts of the Gulf to the much less studied central part. That morphotectonic feature are
the marine terraces, which mainly dominate the eastern part and less the western one.
Consequently, an estimate of the southern margin central part uplift rates would
complete the picture of the uplift rate variations along the entire coast and could add
significant help to the region’s tectonic evolution interpretation.
After a thorough analysis of the marine terraces topographic profiles according
to a graphical method (Lajoie 1986) and a relative dating using a suitable sea-level
curve, uplift rates have been estimated for the following regions; a) Mertikaiika, b)
Kariotika Kamariou for an active and an inactive West Xylokastro Fault, but the second
one is considered accepted, c) Ano Loutro and d) Mentourianika. Based on the data
available and the region’s geomorphology, further research is considered necessary.
The second part of the study, concerns the estimation of the region’s vertical axis
deformation (altitude changes) for the period of 40 years (1967 – 2007), using satellite
and topographic data to create digital elevation and terrain models. The existent data
contain several errors and the exact quantification of the changes is difficult especially
in areas of unstable relief and when the spatial analysis of the data is reduced, while the
qualitative changes are always evident. However, a spatial resolution of 5 m, is able to
capture major changes in parts of the relief, such as the coastal zone where human
intervention is intense. Finally, the resulting altitudinal changes are the constituent of
various components, which are difficult to deduct at this level of research.
