Lineament Analysis in Eastern Anatolian Fault Zone Between Bingöl-Karlıova By Landsat 7 ETM and SRTM DEM Data

45897

Lineament is formally mappable surface properties that correspond to underground structures probabyl and that distunguish easily from the surrounding structures. The research area covers the Eastern Anatolian Fault Zone (EAFZ) between Bingöl-Karlıova. The purpose of study is to determine relationship with faults of lineaments and to define lineaments with image enhancement techniques and by otomatic methods using satellite images and SRTM DEM. The data of this research are 1 August 2002 dated Landsat 7 ETM, SRTM DEM, geology, topography maps and literatüre dataEdgeat Filter is applied to the Landsat 7 ETM. Lineaments automatically obtained in the PCI Geomatica and later lineaments are edited map in the Arcmap. For accuracy analysis buffer zones of 200 m have been created for the faults and the lineaments falling into these zones have been accepted as faults. Lineament density and orientation analysis are made with lineament data and lineaments are compared with fault orientations. As a result of research, ratio of equivalent to faults of lineaments extracted from Landsat 7 ETM is 25,5 %. ratio of equivalent to faults of lineaments extracted from SRTM DEM is 31 %. In addition to zones compatible with DAFZ, presence of other fault zones are observed in lineament density and orientation analysis.
