Abstract We study the influence of particle shape anisot-ropy on the occurrence of avalanches in sheared granular media. We use molecular dynamic simulations to calculate the relative movement of two tectonic plates. Our model con-siders irregular polygonal particles constituting the material within the shear zone. We find that the magnitude of the ava-lanches is approximately independent of particle shape an
