... Rupture Forecast ( Tullis et al. , 2012a ). In this study I describe the viscoelastic earthquake simulator (ViscoSim) of Pollitz, 2009 . Recapitulating to a large extent material previously presented by Pollitz (2009 , 2011 ) I describe its implementation of synthetic ruptures and how it differs from...

...Figure 3. The frequency‐magnitude plot for four earthquake simulators compared with observations shown as a broken red line (fig. 15 of Field et al. , 2008 ). ALLCAL and RSQSim are quite similar to each other and to observations. This is less true for VIRTCAL and ViscoSim due to different...

... deformation model. For most of the simulators in this volume, the medium in which the fault system is embedded is represented by a homogeneous linear elastic half‐space. However, one simulator ( Pollitz, 2012 ), ViscoSim, can include both viscoelastic behavior and layered elasticity. Absolute...

... the implementation of viscoelasticity into the ViscoSim earthquake simulator according to the prescription given in the previous sections. Thus, it is an update of the simulator described by Pollitz (2009) and Pollitz (2012) . Other aspects of ViscoSim are retained in the updated version. In particular...

... ), earthquake simulator for Virtual California faults systems (VIRTCAL) ( Sachs et al. , 2012 ), RSQSim ( Richards‐Dinger and Dieterich, 2012 ), and Viscoelastic earthquake Simulator (ViscoSim) ( Pollitz, 2012 ). Based on the results of Tullis, the simulator that performs the best is RSQSim. Although all...

.... Based on a simplified viscoelastic‐cycle model of fault interaction Pollitz and Schwartz (2008) and Pollitz (2011 , 2012) developed the ViscoSim earthquake simulator, which is the only known simulation code including viscoelastic stress transfer and a layered elastic crust. The variety...

...., Pollitz and Sacks, 2002 ). ViscoSim ( Pollitz, 2012 ) was developed specifically to address that issue. It might be possible to include the effect of viscoelastic relaxation in Quake‐DFN by modulating tectonic loading following the approach adopted in MCQSim. In the simulations presented in this study...
