The formulas and the directions of the forces acted on the ends of the fault in earthquake source located in the tension region distributed radially have been derived theoretically.

The NNE fault system is mainly controlled by tension-torsional stress, and the NNE-NE fault system by these factors: boundary condition, sedimentary facies zone and regional tensional stress.
