| dc.description.abstract | These files are from the numerical simulations conducted in Basu et al., "Nonlocal dissipation far from the rupture tip affects both rupture dynamics and arrest" We found: Linear elastic fracture mechanics is useful for understanding earthquake rupture, but seismological evidence suggests earthquake fracture energy spanning from 1 J/m2 to 10 MJ/m2. Fracture energy is localized to the rupture tip, so high seismological estimates should instead be considered breakdown work Wb, which includes nonlocal energy dissipation, possibly arising from long-tailed secondary weakening (LTSW) that scales with final slip. However, it is unclear if LTSW and associated large Wb causes earthquakes to rupture faster and grow larger or propagate more slowly and arrest easily. We report numerical models of dynamic rupture that illuminate effects of LTSW on rupture propagation and arrest due to heterogeneous initial stress. Our findings indicate that secondary weakening always leads to a higher rupture speed and a larger rupture extent compared to scenarios without it. Additional stress drop associated with secondary weakening does more to “fuel” rupture than larger Wb does to arrest rupture. | |
