| Abstract: | 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.
