We provide a summary of the surface fault ruptures produced by Mw7.8 14 November 2016 Kaikōura earthquake, including examples damage to engineered structures, transportation networks and farming infrastructure direct rupture displacement. also an overview earthquake in context source model estimated ground motions from current (2010) version National Seismic Hazard Model (NSHM) for New Zealand. A total 21 faults ruptured along c.180 km long zone during some that were unknown prior event. The...

Traveltimes between shots from nine marine seismic reflection lines and onshore recorders were used to construct a 3‐D P wave velocity model of the northern Hikurangi subduction margin, New Zealand. From north south Raukumara Basin Peninsula, Moho overriding plate increases in depth 17 ∼35 km. Low velocities 3.5–5.0 km/s are localized within ∼10 km thick prism lower crust immediately updip intersection thrust beneath topographic crest East Cape Ridge Range. Southward, this region low surface...
[1] Structures within the deep crust and upper mantle of a continental back-arc region are imaged with seismic wide-angle reflection refraction profiling. The data from new experiment (MORC) in Central Volcanic Region (CVR) New Zealand, which is active system behind Hikurangi Subduction Zone. Nine 0.4–1.3 ton dynamite shots were recorded on ∼700 seismographs spaced along 120 km-long array. There two important discoveries this study; lower-crust (15–25 km depth) “rift-pillow” rocks where P...

During the second phase of Alpine Fault, Deep Fault Drilling Project (DFDP) in Whataroa River, South Westland, New Zealand, bedrock was encountered DFDP-2B borehole from 238.5–893.2 m Measured Depth (MD). Continuous sampling and meso- to microscale characterisation whole rock cuttings established that, sequence, sampled amphibolite facies, Torlesse Composite Terrane-derived schists, protomylonites mylonites, terminating 200–400 above an Principal Slip Zone (PSZ) with a maximum dip 62°.

A long‐standing question in crustal seismology is the nature of rocks with compressional P ‐wave speeds 7–7.6 kilometers per second that are found beneath continental rift zones [e.g., Cook , 1962]. Two interpretations possible: They either lower rocks, or upper mantle material unusually low velocities because presence a small percent partial melt. An April 2005 explosion experiment set out to explore issue what crust and Taupo Volcanic Zone (TVZ), central North Island, New Zealand. The TVZ...

Abstract Accurate, high‐resolution and sector‐specific greenhouse gas emissions information is increasingly needed for the development of local, targeted mitigation policies. We describe a detailed, spatially temporally resolved CO 2 data product, Mahuika‐Auckland, Auckland, New Zealand, based on Auckland's regional air inventories. Emissions are provided at 500 m spatial resolution 1‐hr time step, level detail not previously available any Zealand city. divide fossil fuel into six sectors...
The largest city in New Zealand, Auckland is home to roughly 1.5 million people -- one third of Zealand's population. Here we assemble a bottom-up inventory Auckland's fossil fuel carbon dioxide emissions from variety data sources. We use these estimates combination with the UrbanVPRM land surface model estimate net balance region. This work part larger CarbonWatch NZ project, which aims produce quickly enough assess and refine ongoing national efforts reach neutrality.
