Determination of the fractal dimension of the active fault data along the east anatolian fault zone

Abstract

The current study has analyzed active fault data along the East Anatolian Fault Zone (EAFZ) apply ing both manual (classic) and modem versions of the box counting method. The EAFZ active fault datasct used for analysis was taken from the Geoscience Map Viewer and the Drawing Editor from the website of the General Directorate of Mineral Research and Exploration. The study covered an area stretching from Karhova in the north to Kinkhan in the south. The fractal analysis of the earthquake surface rupture and the Holocene fault data was performed. Fractal dimensions of the EAFZ active-fault data were calculated for 15 boxes and compared with correlation coefficient values. The calculated fractal dimension values were found to vary with the density of the active-fault data falling into the boxes. The maximum fractal dimension value D-1 was determined for Karliova and its surroundings, which can be associated with the fault density due to the branching geometry.
