From: A new mechanical perspective on a shallow megathrust near-trench slip from the high-resolution fault model of the 2011 Tohoku-Oki earthquake

Fig. 3

Schematic illustration of the subfault geometry. The unit fault-normal vector \(\overline{\mathbf{n} }\) (blue arrow) is derived from the locations of the subfault vertices (gray dots). The unit slip vector \(\overline{\mathbf{s} }\) (red arrow) is derived from the plate convergence vector v (thick black arrow) and the dot product of the fault-normal and the slip vectors (\(\overline{\mathbf{s} }\bullet \overline{\mathbf{n} }=0\))
