Data from: A geology and geodesy based model of dynamic earthquake rupture on the Rodgers Creek-Hayward-Calaveras fault system, California

The Hayward fault in California's San Francisco Bay area produces
large earthquakes, with the last occurring in 1868. We examine how
physics-based dynamic rupture modeling can be used to numerically simulate
large earthquakes on not only the Hayward fault, but also its connected
companions to the north and south, the Rodgers Creek and Calaveras faults.
Equipped with a wealth of images of this fault system, including those of
its 3D geology and 3D geometry, in addition to inferences about its
interseismic creep rate pattern and rock-friction behavior, we use a
finite-element computer code to perform 3D dynamic earthquake rupture
simulations. We find that the rock properties affect the locations and
amount of slip produced in our simulated large earthquakes. Crucial
factors that control rupture behavior in our modeling are the earthquake
nucleation locations, the fault geometry, and the data that reveal where
the fault system is creeping or locked. Our findings suggest that large
Rodgers Creek-Hayward-Calaveras-Northern Calaveras (RC-H-C-NC)
fault-system earthquakes may result from dynamic rupture that starts in a
locked part of the fault system, but is then stopped by the creeping
parts, leading to high magnitude-6 earthquakes; or, from dynamic rupture
that starts in a locked part of the fault system, then cascades through
some of the creeping parts, leading to magnitude-7 earthquakes.
