This study comprises a new focal mechanism solution (OMC) program that can be used for scientific research and educational purposes. In addition, results of applied researches performed in the frame of this study, are also given using this software which is called WinFOC. In order to compute fault plane solutions and investigate kinematics of different fault systems, it is used WinFOC that accepts P-wave first motion polarity technique. In this way, 7 different earthquakes that occurred in our country were analyzed by using this program and obtained results were compared with findings reported by different institutions. The calculations performed with WinFOC were made using interactive graphical interface. In this context, we have determined P-and T-axes with azimuth (phi), dip (delta) and rake (lambda) angles of fault planes. Dip-directions (sigma) were also identified on fault planes with availability of dip-slip faults. Compression and dilatation zones were manually separated from each other by meridians with different range of steps varying in different degrees. In order to interpret beach-balls with kinematics of fault ruptures that are responsible of earthquakes, the program is also capable to plot most acceptable 3-D bloc-diagram with appropriate scale according to slip-rate of dominant strike-type.
