This study focuses on one of these systems, the Karewa Fault and mass transport deposit (MTD), in order to understand the genetic relationship between the fault and the MTD in its hangingwall depocentre, i.e. did the MTD fill existing accommodation space? Did the MTD trigger growth fault displacement? Or is there some other relationship? Most mass transport deposits are elongate in the transport direction and exhibit a length:width aspect ratio of more than 1. However, the 90 km2 Karewa Fault MTD is at least three times wider than it is long, which is atypical for MTDs reported in the literature, where ~80% have a length:width ratio >1. The transport direction of the MTD is to the WNW, as indicated by the location and internal structure of the compressional toe and the headwall scarp region of the Karewa Fault. The structural and sequence geometries on seismic reflection data indicate the MTD formed during the late stage of growth fault activity, and locally truncates the upper part of the Karewa Fault. The MTD is inferred to have originated by local destabilization of the sediment package overlying the Karewa Fault related to the escape of overpressured fluids along the fault. The resulting MTD was translated locally by only a few kilometres. This unusual cause for an MTD also resulted in its atypical length–width–thickness aspect ratios.", }
