Summary:
The focus of this present research (thesis) lies on associating the concept of
integrated coastal zone management with the potential risk of tsunamis in the
Cyclades.
At the beginning of the thesis the meaning and the objectives of integrated coastal
zone management are presented as well as the legislative framework in Greece and
Europe respectively. Furthermore, the natural risks that coastal areas face leading to
tsunami are examined together with the basic features of this phenomenon, its
behavior when it hits a coastal zone and the potential areas of a tsunami outbreak in
Greece.
After that, the focus turns on the geological and geomorphological description of the
area under discussion which mainly consists of the following islands and the sea that
surrounds them: Folegandros, Sikinos, Iraklia, Schoinousa, Koufonisia, Keros,
Amrogos, Astypalaia, Anafi and Santorini. This particular description verifies the
danger of a tsunami creation in the area mainly caused by underwater landslide.
As far as the methodology is concerned, in order to highlight the consequences a
tsunami could have on Southern Cyclades at present time, a certain pattern is
followed concentrating events from all over the world which include certain tsunami
incidents caused by the three categories: earthquake, volcano, and landslide.
Furthermore, we take into consideration two particular events that took place in the
specific area as well as the rate of max run up which each of two events gave and as
well of all world events.
After carefully examining this information, we can conclude to 7 zones with a range
of, which can be observed on the coasts of the island complex. At the same time, by
following this pattern, the coastal zone of each island is designated.
By inserting the data collected in the ArcGIS, the coastal area is divided into zones;
hence the potential risk for every island is illustrated.
This zoning of risk is presented together with the run up rates which have been
documented in the latest tsunami on the island of Amorgos in 1956.
In the next chapter, the effects of tsunami are highlighted starting with a brief
history of the tsunami that took place in the wider area of the Southern Aegean Sea.

Next, the idea of zoning is applied to the current uses of land on the islands paired
with pictures taken from satellites. In this way it is underlined what is going to
happen in case a tsunami hits the area of norther Cyclades and the potential impact
it will have on the residential, tourist, industrial and agricultural areas accordingly.
After stressing the effects, preventive measures are recommended, which are
already applicable to countries which face the phenomenon of tsunamis, while, they
could be implemented in our country as well. An attempt is being made to associate
the measures that have to be taken with the idea of integrated coastal zone putting
emphasis on the fact that taking measures heavily rests on the principles of
sustainable development.
The research is completed reaching to conclusions, most basic one being the one of
the necessity to include the prevention of the risk of a tsunami in every strategy of
the integrated coastal zone management for south Cyclades.
