    The 30 October 2020, Mw 6.6 Sisam (Samos) Earthquake: Interpretation of Strong Ground Motions and Post-Earthquake Condition of Nearby Structures
    (Tekirdağ Namık Kemal Üniversitesi, 2021) Akansel, Vesile Hatun; Özkula, Gülen
    A major magnitude Mw 6.6 earthquake struck offshore of the city of İzmir, Turkey and the city of Neon Karlovasion, Greece which has the epicenter located at north of Sisam/ Samos Island in the eastern Agean Sea on October 30th, 2020. The moment magnitude of the earthquake has been reported variously, such as 6.6, 6.9 and 7.0 by different agencies. Seismic instruments indicate the earthquake originated at a depth of 17.2 and 21 kilometers according to the Disaster and Emergency Management Presidency (AFAD) of Turkey and USGS. Doğanbey Payamlı, Ürkmez, Gümüldür, Kavakdere are the closest coastal villages of İzmir to the epicenter. The earthquake affected the mid-rise buildings located on the soft soil and then, tsunami stroked the coastal villages of İzmir. In this study, the strong ground motion records in a distance range from epicenter to 150 km are analyzed to investigate the characteristic of the ground motions. The post-earthquake field observations mainly for the mid-rise reinforced concrete structures are reported. The spatial distribution of the damage indicates a basin effect within the Bayraklı, Bornova and Karşıkaya regions. The 8-10 story mid-rise buildings affected from the main and aftershocks and the north coasts of İzmir affected from the tsunami were the main observations of this earthquake.
