Splay fault branching from the Hikurangi subduction shear zone: Implications for slow slip and fluid flow

Splay fault branching from the Hikurangi subduction shear zone: Implications for slow slip and fluid flow

Prestack depth migration data across the Hikurangi margin, East Coast of the North Island, New Zealand, are used to derive subducting slab geometry, upper crustal structure, and seismic velocities resolved to ∼14 km depth. We investigate the potential relationship between the crustal architecture, f...

Zusammenfassung:Prestack depth migration data across the Hikurangi margin, East Coast of the North Island, New Zealand, are used to derive subducting slab geometry, upper crustal structure, and seismic velocities resolved to ∼14 km depth. We investigate the potential relationship between the crustal architecture, fluid migration, and short‐term geodetically determined slow slip events. The subduction interface is a shallow dipping thrust at
