We study the temporal and spatial correlations in a one-dimensional model of a heterogeneous fault zone, in the presence of viscoelastic effects. As a function of dynamical weakening and of dissipation, the system exhibits three different "phases": one in which there are no time correlations between the events, a second, in which there are "Omori's law"type temporal correlations, and a third, runaway phase with quasiperiodic system size events.
