SUMMARY
We perform a systematic parameter space study of the seismic response of a large fault
with different levels of heterogeneity, using a 3-D elastic framework within the contin-
uum limit. The fault is governed by rate-and-state friction and simulations are performed
for model realizations with frictional and large scale properties characterized by different
ranges of size scales. We use a number of seismicity and stress functions to characterize
different types of seismic responses and test the correlation between hypocenter loca-
