Διερεύνηση του γεωπεριβάλλοντος της νήσου Ικαρίας

Greek

Present morphological and tectonic image of Ikaria island is the complex result
of both the temporal evolution of the island, as part of the geodynamical
evolution of the Hellenic Arc, especially that of the last stages (from the
upper Miocene and after), and the exogenous factors.
According to field data and their analysis, computing and estimation which took
part with the use of modern technologies (use of GIS, analysis of geographical
and descriptive databases) new maps of Ikaria Island were developed. The
morphotectonic units of the island were defined based on their special features
and more precisely on the lithological differentiation (granite, metamorphic
rocks and post alpine formations) as well as the complex ductile and brittle
structures (large scale ductile shear-zones and brittle detachment faults,
normal faults, strike-slip transfer faults and join sets) and the morphological
features (slope distribution, asymmetry of the drainage system, planation
surfaces, morphological discontinuities etc).
The synthesis of the special features of each morphotectonic unit in
combination with the human impact (fires, overgrazing etc), defines the kind,
the intensity and the geographical localization of the natural hazards which
occur in various sites of the island, such as landslides, erosion, floods,
relief changes, coastline changes etc.
