Abstract (2. Language): 
Earthquake-induced deformation structures which are called seismites may helpful to clasify the paleoseismic history of a location and to estimate the magnitudes of the potention earthquakes in the future. In this paper, seismites were investigated according to the types formed in deep and shallow lake sediments. Seismites are observed forms of sand dikes, introduced and fractured gravels and pillow structures in shallow lakes and pseudonodules, mushroom-like silts protruding laminites, mixed layers, disturbed varved lamination and loop bedding in deep lake sediments. Earthquake-induced deformation structures, by benefiting from previous studies, were ordered according to their formations and earthquake magnitudes. In this order, the lowest eartquake's record is loop bedding and the highest one is introduced and fractured gravels in lacustrine deposits.

Abstract (Original Language): 
Sismit olarak da adlandırılan deprem kökenli deformasyon yapıları, bir bölgenin paleosismik tarihçesini aydınlatmada ve o bölgede gelecekte karşılaşılabilecek olası deprem büyüklükleri hakkında önemli ip uçları verebilir. Sismitler bu makalede, derin ve sığ göl çökellerinde oluşan tiplerine göre incelenmiştir. Sismitler, göl kıyısı çökellerinde kum daykları, sokulum yapmış ve kırılmış çakıllar ve yastık yapıları şeklinde gözlenirken, derin göl çökellerinde ise yalancı yumrular, mantarımsı yapılar, karışmış tabakalar, bozulmuş varv laminaları ve ilmeksi tabakalanma yapısı olarak görülür. Deprem kökenli deformasyon yapıları, daha önce yapılan çalışmalardan yararlanılarak, göl çökellerindeki oluşumlarına ve deprem büyüklüklerine göre bir sıralama yapılarak verilmiştir. Bu sıralamaya göre, çökellerde en düşük deprem büyüklüğünün kaydı ilmeksi tabakalanma yapıları, en büyük deprem büyüklüğünün kaydı ise sokulum yapmış ve kırılmış çakıl yapılarıdır.
