From: Resolving Fine-Scale Heterogeneity of Co-seismic Slip and the Relation to Fault Structure
Correlation of slip variability (black line) to surface trace complexity.
Slip profiles for (a), Landers and (b), Hector Mine (each plotted to same scale), where colored lines indicate individual fault slip profiles. Below slip profiles we plot the fault traces mapped in our correlation results (where colored traces correspond to individual colored slip profiles above) and the fault traces mapped in the field immediately following the earthquakes (red lines)28,29. Areas of long-wavelength slip (green, >2 km along-strike distance) correlate to large-scale jogs and bends in the fault trace, while intermediate-wavelength (blue, 0.2–2 km along-strike distance) and short-wavelength (red, <0.2 km along-strike distance) variability tends to correlate with progressively smaller-scale geometrical features. The >2 km category of slip variation is chosen so as to relate macroscopic variations of fault slip to macroscopic areas of structural complexity along the surface rupture, similar to the approach of ref. 30 and ref. 31. The shortest range of slip variation is chosen as the shortest resolvable variation in fault slip that we can observe along the rupture, with the medium wavelength category (0.2–2 km) simply defined as the variation of slip found between the two end-members.
