“…We use the characterization “soft” to describe a diffused tectonic boundary, not marked by a discrete fault zone, but consisting of multiple, smaller and scattered faults which individually accommodate most of the region's deformation. These faults are mainly pure ∼E‐W normal structures onshore western Turkey, and as we approach the Turkish coasts and move westwards offshore, the typical pure ∼E‐W normal faults coexist with conjugate ∼NE‐SW strike‐slip structures (Aktar et al., 2007; Aktuğ et al., 2009; Uzel et al., 2013; Yilmaz & Gürer, 2023). This diffuse zone of deformation and the faults that receive it could possibly reflect the fact that the Aegean microplate and the Anatolian plate are not separated in a straightforward way, that is, by means of a well‐defined tectonic boundary, but with this wide transition zone which accommodates the curved stretching of the entire plate system whose direction and rate of motion changes as we pass from the westward moving Anatolian plate to the faster and SW moving Aegean microplate.…”

We present a new geodetic strain rate and rotation rate model for Greece that has been derived using a highly dense GPS velocity field. The spatial distribution and the resolved rates of the various velocity gradient tensor quantities provided updated constraints on the present‐day upper crustal deformation in the region and revealed new details not reported previously. The spatial distribution of the second invariant demonstrated that the overall magnitude of strain rates is highest across two well‐defined provinces. The first follows the North Anatolian Fault and its two branches within the north Aegean, crosses central Greece and through the Gulf of Corinth it terminates in western Greece, while the second encompasses the extensional province of western Turkey and the eastern Aegean Sea islands. Our estimates revealed that shearing affects some of the fault‐bounded grabens of central Greece that lie to the SW of the North Aegean Basin implying considerable oblique extension. We identified a narrow region of counterclockwise rotation whose location and kinematics have been induced by the net effect across the intersection of the clockwise rotating domains of western and central Greece. The Aegean microplate and the Anatolian plate are separated by a wide transition zone which accommodates the curved stretching of the entire plate system. In both edges of the Hellenic forearc the dominant mode of crustal strain is E‐W extension. We found that earthquakes of M ≥ 5.6 are spatially well‐correlated with high‐strain areas, indicating that strain rate mapping could be used to inform future probabilistic seismic hazard analyses.

Köyceğiz Region offers a fascinating beauty with its lakes, long sandy beaches, rivers, as well as mountains and hills covered with pine, sweetgum and mastic tree forests. Therefore, there is an intense visitor activity in the region. In addition, there are well-marked, year-round hiking and cycling routes around the mountains and lakes in Köyceğiz. On some of these routes, eco-sites have been identified and explanatory panels have been placed. However, geosites have not been identified in the region for the geological structures that carry all this ecological diversity. In fact, the Köyceğiz Region is one of the typical regions that presents geological stories from the paleotectonic and neotectonic periods together. Our proposal in this study is to select geosites on existing nature routes that reflect the geological story of the region and to develop explanatory panels for them. In this study, we have identified geosites located on nature tourism routes in the region and described their geoscientific content. By installing panels on geosites, the geo-ecological systems located on the routes will be able to explain themselves to travelers. This is a new geo-eco-tourism approach with a small budget, aimed at existing visitors in the region, without trying to attract visitors to the area.
