Abstract
The conservative Olami–Feder–Christensen model of earthquake give a power-law decay in the size distribution of events, but does not give correlation in the event times. We modify the model so that the thresholds vary temporarily after each event. Our model also gives a power-law decay in the size distribution. Three typical regimes can be identified in the interevent time distribution: At large times, it decays exponentially. At intermediate times, a power-law decay is observed. At small times, it becomes time-independent. A sequence of events may be divided into clusters, each consisting of a mainshock and aftershocks (foreshocks). Aftershocks have a power-law decay in the after-time distribution and foreshocks have less in the fore-time distribution.
