eri n g subsurface rupture length (km); RW — downdip rupture width (km); RA — rupture area (km2); MD — maximum displacement (m);

a SRL—surface rupture length (km); RLD

AD — average displacement (m). b SS— strike slip; R — reverse; N — normal.

c Regressions for reverse-slip relationships shown in italics and brackets are not significant at a 95% probability level.
