Abstract: 

In order to study the crust in Azarbaijan area, 2654 earthquakes data recorded in 8 stations of Azarbaijan network, during 3.5 years, are processed. 42 earthquakes of the recorded data occurred in this area. By making 42 profiles, including one source and two stations, P-wave travel times are calculated. Then by choosing an initial three-layer model, Depth and velocity parameters of each layer are optimized. The results of optimization are used for contour map plots of velocity and depth variations. Velocity discontinuities and sudden variation in depth, observed on the maps, are related to the faults in the area. Velocity variations with depth were 3.5-7.5km/s and depth variations of first and second interface respect to the surface were 4.5-6km and 18-22km respectively.
