Why do fast earthquakes accelerate dramatically while slow ones are not able to? In this study, we explore the physical origins of various types of events in a particle-based simulation of fault slip. Our model simulates a vertical crustal strike-slip fault in two dimensions, viewed from the top. We use an assemblage of about 14,000 particles, bonded to impart cohesion at all contacts except along a pre-defined fault line of 50 km length.
