“Virtual California” (VIRTCAL) is an earthquake simulator developed in several steps by the Rundle group (Rundle et al. 2005, 2006; Yikilmaz et al. 2011; Sachs et al. n.d.; Tullis et al. 2012a,b) .

This is a geometrically realistic numerical simulation of earthquakes occurring on the San Andreas fault system and includes all major strike-slip faults in California. VIRTCAL includes, in its algorithm, a rupture weakening mechanism. Among its applications, there are earthquake hazard assessment and earthquake forecasting (Rundle et al. 2005). Later on, VIRTCAL was named “Virtual Quake” (VQ), a greatly improved, open source, modularized C++ code, including fault model-building tools, simulation analysis script and Python library “quakelib” (Schultz and Wilson 2015). In addition to producing probabilities for earthquake scenarios, VQ can generate samples of co-seismic deformations, gravity changes and InSAR interferograms (Schultz et al. 2015). VQ has been tested on the seismicity of various seismic regions of the world, such as Mexico (Yoder et al. 2015), California (Schultz et al. 2017) and Iran (Khodaverdian et al. 2016a,b).
