Numerical simulations of fractures of the Earth's crust are made using the Extended Distinct Element Method (EDEM), which has been found to be suitable for simulating the behavior of a medium from a continuous state to a discrete state following the total fracture process. Two sets of numerical experiments are conducted: 1) the boundaries of a model are sheared to cause a fracture; 2) the state just prior to the rupture of the Earth's crust is simulated first and then parameterization is done to incite a rupture. From the first set of experiments, progressive development of cracks inside the medium and dilatation as a result of pervasive cracks are simulated. The shear forces show a stick-slip type of behavior.
