Özet:

 In this study, it is aimed to determine the relative tectonic activity of faults controlling Varto Basin with geomorphic indices. Varto Basin is located in the southeast of Karlıova, between Bingöl and Serafettin Mounts. Varto Fault, which intersects with the East Anatolian Fault in Karlıova and the continuation the North Anatolian Fault towards southeast, has been effective in the formation of the basin. Being right lateral strike slip, Varto Fault starts in the east of Karlıova Triple Junction and continues towards southeast in the form of a zone. Due to this location, tectonic activity in and around the basin is very high. The young tectonic movement of the basin has been revealed by geomorphic index analysis method. In these analyses, digital elevation model DEM, stream, fault and geology data were used as the basic data set. A total of 43 sub-basins reflecting tectonic activity have been identified around the basin periphery and on Varto Fault zone VFZ. For this purpose, hypsometric integral Hi, hypsometric curve Hc, basin asymmetry factor AF, drainage basin shape Bs, stream length-gradient index SL, channel sinuosity S and elongation ratio Re analyses were performed. Along with the basin analyses, the measurements of mountain front sinuosity ratio Smf and valley floor width-to-valley height ratio Vf, which are frequently used in the determination of active tectonics, and streams longitudinal profile analyses were done in the basin. According to the results of the analyses, tectonic activity classes of the basins were determined and their distributions were shown. According to these results, except for the two basins in the south of the Varto basin and one located in the VFZ, all others fall into very high and high tectonic activity classes. Index results, earthquakes, hot and cold sources along the fault zone and geomorphological figures prove that active tectonics are intense in and around Varto Basin.

 Bu çalışmada Varto Havzasını denetleyen fayların göreceli tektonik aktivitesinin jeomorfik indislerle belirlenmesi amaçlanmıştır. Varto Havzası, Karlıovanın güneydoğusunda Bingöl Dağı ile Şerafettin Dağı arasında yer almaktadır. Havzanın oluşumunda, Karlıovada, Doğu Anadolu Fayı ile kesişen, Kuzey Anadolu Fayının güneydoğuya doğru devamı niteliğinde olan Varto Fayı etkili olmuştur. Bu konumu nedeniyle havza ve çevresinde tektonik hareketlilik çok yüksektir. Havzanın genç tektonik hareketi jeomorfik indis analizleri yöntemiyle ortaya konulmuştur. Bu analizlerde sayısal yükselti modeli sym, akarsu, fay ve jeoloji verileri temel veri seti olarak kullanılmıştır. Havza çevresi ve Varto Fay Zonu VFZ üzerinde tektonik aktiviteyi yansıtan toplam 43 alt havza belirlenmiştir. Bu amaçla hipsometrik integral Hi, hipsometrik eğri He, havza asimetri faktörü AF, drenaj havzası şekli Bs, akarsu uzunluk-gradyan indeksi SL, yatak kıvrımlılığı S ve uzama oranı Re analizleri yapılmıştır. Havza analizleri ile birlikte aktif tektoniğin belirlenmesinde sık kullanılan dağ önü sinüslülük oranı Smf ve vadi tabanı genişliği-vadi yüksekliği oranı Vf ölçümleri ile havzadaki akarsuların boyuna profil analizleri yapılmıştır. Analiz sonuçlarına göre havzaların tektonik aktivite sınıfları belirlenerek dağılışları gösterilmiştir. Bu sonuçlara göre havza güneyindeki iki küçük havza ile VFZdeki bir havza dışındaki diğer havzaların tamamı çok yüksek ve yüksek tektonik aktivite sınıfında yer almaktadır. İndis sonuçları, yaşanan depremler, fay zonu boyunca çıkan sıcak ve soğuk kaynakları, jeomorfolojik şekiller Varto Havzası ve çevresinde aktif tektoniğin güçlü olduğunu kanıtlamaktadır.
