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 43.1 km long and 16 km wide rupture, which slips 1.42 …

In recent years, seismicity has increased considerably in the Aegean Sea region and there have been earthquakes in which people lost their lives. The major earthquakes, Kos Island-Gökova Bay (Mw = 6.6), Lesvos Island-Karaburun (İzmir) (Mw = 6.2) and Samos Island-Aegean Sea (Mw = 6.9) occurred in the Aegean Sea and affected Aegean region strongly. Within the scope of this study, the seismic b-value of these major earthquakes was calculated in order to perform earthquake statistical analysis. Seismic a and b-values within the first 24 h and 14 days after the mainshock determination of Kos Island-Gökova Bay, Lesvos Island-Karaburun (İzmir) …


Impacts Of The 2020 Samos Earthquake On The Modeling Of Ancient Seismic Events, Stathis Stiros Jan 2021

Impacts Of The 2020 Samos Earthquake On The Modeling Of Ancient Seismic Events, Stathis Stiros

The 2020 Samos, M7.0 earthquake was characterized by an unusual bi-modal-type distribution of damage: limited damage in the nearfield (especially northern Samos coast) and serious localized damage in multi-story buildings in the far field (İzmir area). This pattern is not consistent with the typical distribution of isoseismal lines, and it seems not to represent an isolated effect; the 2014 Samothraki- Gökçeada M6.9 earthquake, for example, may in fact represent a parallel, though at smaller scale. For this reason, the damage pattern of the Samos earthquake may characterize historical earthquakes in the wider region, and perhaps explain, among others, some apparently …
