In this study, the
relationship of landslides with lithological units and fault lines on the East
Anatolian Fault Zone (EAFZ) between Palu (Elazığ) and Bingöl, was evaluated. In
the study area, which is located within the EAFZ, Göynük to the northeast, Palu
Segment to the southwest, Genç Segment to the south of Bingöl plain and Gökdere
Uplift in the intersection area form the main tectonic structures. In addition,
the Karakoçan Fault Zone (KFZ) cutting the EAFZ in NW-SE direction between Palu
and Bingöl corresponds to another important structure (system). The area, which
is located in a region where a number of faults intersect, is tectonically very
active. This situation has affected the morphology and caused the formation of
many landslides along fault lines. In order to determine the relationship
between the landslides observed in this area and lithological and tectonic
structures, landslide magnitude and distribution analyses were performed by
means of Geographical Information Systems. For this purpose, the landslide
inventory map and the database were reproduced controlling the satellite images
in field studies. Similarly; geological and tectonic maps were prepared considering
previous studies. Landslides created in vector format were converted into
raster format and overlain with lithological and tectonic maps, and then the
relationship between landslides and lithology-fault lines were determined.
According to these results, 59% of landslides occur in Upper Miocene-Pliocene
agglomerate and tuff units and 10% of them in Eocene carbonate units. According
to these data, almost 70% of the landslides in the study area occurred in two
units. Considering the relationship between landslides and fault lines 64% of
the landslides are observed at 0-1000 m distances to the fault lines. As a
result, there is an important relationship between lithological features and
fault lines. The fact that landslides have occurred along the fault lines in
the north of Murat Valley shows that the landslides are triggered more by earthquakes
when compared with those triggered by the hydro meteorological events.
