Geodetic networks data and modelling

A submarine area close to the Turkish and Greek border between the cities of Samos-Greece and Seferihisar-Turkey has been shaked on October 30, 2020 by a Mw= 6.9 earthquake. In this study, the finite source mechanism of the Samos earthquake was investigated using geodetic methods and the coseismic behavior of the earthquake was modeled. The observed coseismic displacements at 62 sites were inverted for the fault geometry and the slips. The mainshock did not generate an on-land surface rupture. However, the uniform slip modeling shows a finite source of 43.

The morphotectonic features of the TGFZ and the distribution of the epicenters of earthquakes over magnitude 5.0 show that this fault zone remains active today. In this study, the deformation of the TGFZ is determined with high sensitivity using geodetic measurements. To obtain accurate information about the deformation of the TGFZ, 24 GNSS sites and two continuously operating reference stations were constructed in the southern part of the TGFZ. Between 2018 and 2020, Global Navigation Satellite Systems (GNSS) measurements were made on this network.
