The geotechnical lateral variations of the upper crust of the Eastern Anatolian were investigated using amplitude decay, Quality factor, seismic velocity and Poisson’s ratio. The average Poisson’s ratio was calculated as 0.2988 for the whole study area. QPand QSaverage quality factor were determined as 35 and 57, respectively and average δPand δSvalues were determined as 0.0149 and 0.0163 for the whole study area. The lowest QS/QPvalue 1.479 and the highest VP/VSvalue 1.194 are found at the Palu station. The highest VP/VSvalue, Poisson’s ratio and quality factor rates were found in and around Kemaliye. The estimated Poisson’s ratio values for the six stations ranged from 0.117 to 0.680 highlighting the regional differences in the seismodynamic of the crust. The entire study area is divided into different geotechnical regimes according to the lateral distributions of the seismodynamics properties. Study results showed once again that the fracture density and dimensions is associated with seismodynamics properties which are the changeable pressure ratios of the upper crust. |
