Original Title:
Morphotectonic Analysis of the North Aegean and Skyros Basins
Translated title:
Morphotectonic Analysis of the North Aegean and Skyros Basins
Summary:
The current thesis focuses on studying the North Aegean Basin and Skyros Basin using
bathymetric data and its derivatives. The goal is to analyze the morphotectonic features based on morphological criteria and to track fault lines in the submarine area of the aforementioned basins. A Digital Terrain Model (DTM) of 105x105 meters resolution was used (by the European Marine Observation and Data Network) in ArcGIS. The derivatives of this DTM are; Slope, Shaded Relief, 3D Models Contours, and the Synthetic Map. The North Aegean and Skyros Basins are the Western branches of the North Anatolian Fault and are tectonically active areas. The Skyros Basin has a similar structure to the neighboring
North Aegean Basin but has smaller dimensions and lower deformation rates which is
documented by the shallower depths and the smaller width. Both basins are characterized by
NE-SW trending segmented faults that constitute the North Anatolian Fault in the eastern part,
and NE-SW faults that dominate the western part and consist of marginal faults.
The morphotectonic analysis shows that these fault segments are active since their location
coincides with the areas that present abrupt changes in slope. Consequently, its an area prone
to seismic events that in their turn can trigger geological phenomena like submarine landslides with a tsunamigenic potential that could result in catastrophic events.
