Summary:
This thesis integrates geomorphology, structural geology and geological
mapping at Dionysos area, NE Attica Greece, in order to investigate the active
or inactive character of the major tectonic structure that forms, the Northern
slopes of Penteli Mountain. Dionysos Fault zone is the fault that bounds the
small Dionysos graben, trending NW-SE with length up to 16 km. This fault
poses a significant risk to the plain of Athens since it is located only 25 Km
from the center of Athens. In addition several districts are situated on its
immediate hangingwall such as, Dionysos, Nea Makri and Marathonas. This is
important following the destructive 1999 Ms 5.9 that ruptured an unknown
since then, fault that resulted 143 fatalities (Pomonis, 2002). Thus, the main
aim of this study is to examine the largest NW-SE tectonic structure in the
wider Attica region from the Neotectonic point of view as well as its role in
terms of seismic hazard in the overall area. This fault is studied in detail
based on its postglacial scarp, the morphological analysis, the analysis of the
drainage network and the catchments that are influenced by the footwall
uplift, the geological regime of the wider area, the analysis of 3 morphometric
parameters that in conjuction with the high resolution surface data revealed a
wealth of information.
