A schematic diagram showing the rupture-velocity dependence of the fault slip \(D\), slip velocity \(\dot{D}\), and slip acceleration \(\ddot{D}\). The vertical axis \(t^{\prime}\) represents the time normalized by the rupture duration \(\Delta {T} = {{\sqrt {S/2\pi } } \mathord{\left/ {\vphantom {{\sqrt {S/2\pi } } {\overline{v}_{{\text{r}}} }}} \right. \kern-0pt} {\overline{v}_{{\text{r}}} }}\) (\(S\): the final fault area, \(\overline{v}_{{\text{r}}}\): the average rupture velocity)
