computational model for an intraplate earthquake source, comprising of three blocks and two intersection faults, is analysed by using a two-dimensional Distinct Element Method. The Mohr-Coulumb model (M-CM) and Continuously-Yielding model (C-YM) of rock discontinuities are used to simulate the behaviour of the faults. Stick-slip phenomena are obtained for both models. The results support the idea that the nucleation of an intraplate earthquake starts at the intersects of faults
