Introduction
This supporting material introduces the basics of the discrete element
method (DEM), as well as the experimental model setup, simulation
workflow, and calculation of cumulative changes in stress. Moreover, we
tabulate the important mechanical and numerical parameters used to build
the initial models. Finally, we tabulate the published parameters that
we used to constrain/calibrate our models for 1960 Valdivia and 2010
Maule rupture segments.
