Rupture dynamics and ground motion from 3‐D rough‐fault simulations (2013, background): “…and segmentation [e.g., Ben-Zion and Sammis, 2003; Bryant, 2005] to smaller-scale features such as topographic variations on the fault slip surfaces [e.g., Power and Tullis, 1991; Renard et al., 2006; Sagy et al., 2007; Sagy and Brodsky, 2009; Candela et al., 2009, 2012; Bistacchi et al., 2011].”
Precursory Slow Slip and Foreshocks on Rough Faults (2020, background): “Perhaps the most ubiquitous and best characterized source of heterogeneity is ge-82 ometrical roughness: faults are fractal surfaces (Power et al., 1987, 1988; Power & Tullis, 1991; Sagy et al., 2007; Candela et al., 2009, 2012; Brodsky et al., 2016).”
Characterization of Fault Roughness at Various Scales: Implications of Three-Dimensional High Resolution Topography Measurements (2008, methodology): “In the present study, we use new roughness data to extend the type of measurements made by RENARD et al. (2006) and SAGY et al. (2007) and propose a parametric study of the statistical results of fault topography, using multiple signal processing tools.”
Nonplanar Faults: Mechanics of Slip and Off-fault Damage (2009, background): “For natural fault surfaces the exponent H takes values in the range 0.5–1.0 (BROWN and SCHOLZ, 1985; OKUBO and AKI, 1987; POWER and TULLIS, 1991; SAGY et al., 2007).”
