24 January 2020, Sivrice-Elazig-Turkey Earthquake Reconnaissance Report

On January 24, 2020 20:55:11 (UTC), a moment magnitude Mw 6.8 (AFAD) or 6.7 (USGS) earthquake occurred on the East Anatolian Fault zone, due to a NE-SW strike-slip fault rupture along the Sivrice-Pütürge Segment in Elazığ, Turkey. Within the confines of this project, the findings of geological, seismological and geotechnical and structural reconnaissance studies as well as preliminary field investigation studies are published. In addition to geological and geotechnical evaluations in the course of reconnaissance studies, some typical lifeline and superstructure damage examples are also given. Independent engineering groups composed of earth scientists, geological, geophysical, and civil engineers have compiled and documented perishable data immediate upon Elazığ-Sivrice earthquake.


Geotechnical reconnaissance findings of the October 30 2020, Mw7.0 Samos Island (Aegean Sea) earthquake
Ziotopoulou, Katerina; et. al. (2022-11-01)
On October 30, 2020 14:51 (UTC), a moment magnitude (Mw) of 7.0 (USGS, EMSC) earthquake occurred in the Aegean Sea north of the island of Samos, Greece. Turkish and Hellenic geotechnical reconnaissance teams were deployed immediately after the event and their findings are documented herein. The predominantly observed failure mechanism was that of earthquake-induced liquefaction and its associated impacts. Such failures are presented and discussed together with a preliminary assessment of the performance of ...
Evaluation of alluvial deposits in Gemlik basin in terms of earthquake codes.
Avşar, Ulaş; Doyuran, Vedat; Department of Geological Engineering (2006)
Gemlik County is located in the Marmara Region (NW Turkey), which has been affected by destructive earthquakes sourced from North Anatolian Fault System throughout its history. The bulk of the settlement rests on alluvial deposits of the Gemlik pull-apart basin. So, it is vital to investigate the foundation soils in this basin and the response of them to earthquakes. Many earthquake codes were established by the authorities in different countries of the world to estimate the possible ground shaking and seis...
Just how prescient are our building damage predictions?
Gulkan, P; Bakır, Bahadır Sadık; Yakut, Ahmet; Yilmaz, MT (2003-05-13)
Adapazari was the scene of spectacular structural damage as well as widespread liquefaction after the earthquake of August 17, 1999. Damage patterns observed are re-examined to investigate whether they are indicative of a consistent trend explicable in terms of the building attributes and/or site conditions. 301 buildings that had collapsed fully have been re-evaluated from their design blueprints. An examination based solely on structural attributes, including data from other sets of building assessment pr...

An earthquake of MW = 6.1 occurred in the Elazig region of eastern Turkey on 8 March 2010 at 02:32:34 UTC. The United States Geological Survey (USGS) reported the epicenter of the earthquake as 38.873°N-39.981°E with a focal depth of 12 km. Forty-two people lost their lives and 137 were injured during the event. The earthquake was reported to be on the left-lateral strike-slip east Anatolian fault (EAF), which is one of the two major active fault systems in Turkey. Teams from the Earthquake Engineering Rese...
Seismic performance of mid-rise reinforced concrete buildings in Izmir Bayrakli after the 2020 Samos earthquake
Demirel, Ismail Ozan; Yakut, Ahmet; Binici, Barış (2022-07-01)
© 2022 Elsevier LtdOn October 30th 2020, offshores of Samos Island, Greece was hit by a shallow earthquake of Mw = 6.9 moment magnitude. Located 76 km away from the earthquake's epicenter, the mid-rise reinforced concrete (RC) building stock of the densely populated Izmir Bayrakli district experienced the most severe structural damage. Although the horizontal peak ground acceleration recorded at the site (PGA = 0.11 g) was well below design values recommended by the past and the present Turkish seismic code...
