Özet:

 In this study, the reflections of the Sivrice-Elazig earthquake on geomorphology and the linear lines formed in the Karakaya Dam Lake after the earthquake have been analysed. On 24th 2020, a 6.8 magnitude earthquake occurred in the village of Çevrimtas, the epicenter of which is located in Sivrice district to the south of Elazig. In the earthquake, 41 people lost their lives, 37 of them in Elazig and 4 of them in Malatya, and tens of thousands of buildings were heavily damaged. After the earthquake on 30th January 2020, It was reported as water or gas outflow by a group of researchers doing research in the field that white lineaments on the dam were observed overlapping with the fault. However, after this report, it has been observed through field studies that these lineaments have recurred in the same areas on different dates. In the first field observations, the presence of foam and plant fragments in the white linear lines coinciding with faults that the white lineaments are outgassing have been found suspicious. For this reason, in the areas where East Anatolian Fault zone offsets Euphrates Valley, an experiment has been done by leaving straws and foam on the dam lake. According to the experiments results, It was observed that the material left in the absence of the wave was randomly dispersed, and that foam formed by the wave onset and the material left on the surface of the water were aligned in the same direction with the fault and formed white linear lines. These data show that the white linear lines formed on the lake surface are a special form caused by the wave effect, depending on the morphology and air movements, apart from the gas outflow.

 Bu çalışmada, Sivrice-Elazığ depreminin jeomorfolojiye yansıması ve depremden sonra Karakaya Baraj Gölünde oluşan çizgisel hatlar analiz edilmiştir. 24 Ocak 2020 tarihinde, Elazığın güneybatısında, merkez üssü Sivrice ilçesine bağlı Çevrimtaş köyünde 6.8 büyüklüğünde şiddetli bir deprem yaşanmıştır. Bu depremde 37si Elazığda, 4ü Malatyada olmak üzere 41 kişi hayatını kaybetmiş ve on binlerce bina ağır hasar almıştır. Depremden sonra, sahada araştırma yapan bir grup araştırmacı tarafından 30 Ocak 2020 tarihinde, Doğanyol kuzeyinde Karakaya Baraj Gölü üzerinde gözlenen ve fayla çakışan beyaz çizgisellikler, su veya gaz çıkışı olarak rapor edilmiştir. Ancak bu rapordan sonra farklı tarihlerde aynı alanlarda yapılan arazi çalışmalarında bu çizgiselliklerin tekrar oluştuğu görülmüştür. İlk arazi gözlemlerinde faylarla çakışan beyaz çizgisel hatların içerisinde köpük ve bitki parçalarının varlığı, beyaz çizgiselliklerin gaz çıkışı olduğunu şüpheli hale getirmiştir. Bu amaçla Doğu Anadolu Fayının Fırat Vadisini ötelediği alanlarda baraj gölü üzerine saman ve köpük bırakılarak deney yapılmıştır. Deney sonucunda dalganın olmadığı dönemde bırakılan malzemenin şekilsiz dağıldığı, dalganın başlaması ile oluşan köpükler ve su yüzeyine bırakılan malzemenin fayla aynı doğrultuda dizilerek beyaz çizgisel hatlar oluşturduğu gözlemlenmiştir. Bu veriler göl yüzeyinde oluşan beyaz çizgisel hatların gaz çıkışı dışında morfoloji ve hava hareketlerine bağlı, dalga etkisiyle oluşan özel bir oluşum olduğunu göstermektedir.
