Translated title:
Identification of the submarine geohazards (landslides, volcanic eruptions, earthquakes, tsunamis) in the Aegean Sea
Summary:
The particular undergraduate thesis will focus on the identification of the submarine geohazards such as landslides, volcanic eruptions, earthquakes and tsunamis in the Aegean Sea. We will provide details for the geotectonic position of the Aegean Sea in the eastern Mediterranean and for the geotectonic evolution of the area, both before and during the Tertiary age in the 2nd chapter. In the 3rd chapter we will analyze the morphology of the Aegean, its differentiation in basins and sub-basins from the northern (North Aegean Basin) to the southern (Cretan Basin) part, as also one of the many geohazards that can occur in this area, the submarine landslides. Two of the biggest and most studied submarine landslides which occurred in the Santorini-Amorgos Tectonic zone (SATZ) and the North Aegean Basin respectively, will be analyzed afterwards. Then, in the 4th chapter there will be reference to the Greek Volcanic Arc as well as to the islands that compose it, while it will be represented how it migrated in time (from 110 ma to its present day position). The volcanic activity that indicates the modern Greek Volcanic Arc will be described, while the most important volcanic eruptions that occured in it will be analyzed. Later on, (in chapter 5) the seismicity of the Aegean will be presented and specifically the largest earthquakes that took place underwater will be reported. In the present thesis we examine the earthquakes from 1954 to 2001, but apart from these, submarine earthquakes with the largest magnitude (Richter scale) of the last 3 years (2017 -2020) will be also cited. In the 6th chapter we will analyze the last geohazard that can be observed in the Aegean Sea, the tsunamis and their connection with the submarine earthquakes, landslides and the volcanic activity. At last, the methodology followed in order to create the maps which we used in this thesis will be reported in details, by which the submarine geohazards as well as the morphotectonic structure of the wider Aegean Sea can be represented.
