From: Locking on a megathrust as a cause of distributed faulting and fault-jumping earthquakes

Fig. 4

The locking lines (thick red line) separate freely slipping (light brown region) from locked (light blue region) parts of the megathrust, and bifurcate at the southwestern edge of subducted oceanic plate (the transition between the subducted oceanic and continental Pacific plate is shaded light green). Both the locking line and rupture zone of the 2016 Mw7.8 Kaikōura earthquake cross-cut major crustal faults. The oblique continental collision also involves slip on a mid-crustal detachment beneath the Southern Alps (Supplementary Fig. 6).
