Coseismic coastal deformation is often used to understand slip on offshore faults in large earthquakes but the 2016 MW7.8 Kaikōura earthquake multiple ruptured across and sub-parallel coastline. Along ∼110 km of coastline, a rich dataset comprising airborne lidar differencing, field surveying satellite geodesy reveals highly variable vertical displacements, ranging from −2.5 6.5 m. These inform refined model for which incorporates changes inclusion an reverse crustal fault that accounts...

Abstract We use a mapped landslide inventory coupled with 2‐m resolution vertical difference model covering an area of 6,875 km 2 to accurately constrain volume‐area relationships. the calculate source volumes for landslides triggered by M W 7.8 Kaikōura, New Zealand, earthquake 14 November 2016. Of 29,519 in inventory, 28,394 are within analysis area, and these, we have calculated volume 17,256 areas that ≥90% free debris. landslides, about 80% classified as soil or rock avalanches...
Tens of thousands landslides were generated over 10,000 km2 North Canterbury and Marlborough as a consequence the 14 November 2016, Mw7.8 Kaikōura Earthquake. The most intense landslide damage was concentrated in 3500 around areas fault rupture. Given sparsely populated area affected by landslides, only few homes impacted there no recorded deaths due to landslides. Landslides caused major disruption with all road rail links being severed. affecting State Highway 1 (the main link South Island...
Abstract High‐resolution, three‐dimensional (3‐D) measurements of surface displacements during earthquakes can provide constraints on fault geometry and near‐surface slip also quantify on‐fault off‐fault deformation. However, are often hampered by a lack high‐resolution preearthquake elevation data, such as lidar. For example, lidar for the 2016 M W 7.8 Kaikōura, New Zealand, earthquake only covers ≲10% ~180 km mapped ruptures. To overcome lidar, we measure 3‐D coseismic Kaikōura using point...
Abstract Landslide dams, forming when a landslide blocks watercourse, are significant components of slope-river systems. Dams can fail suddenly and catastrophically, threatening downstream populations structures. So it is important to understand where they could form, how long persist in the landscape, extent inundation once fail. To investigate dam formation, longevity, stability effectively Aotearoa New Zealand, we present version 1.0 Zealand Dam Database (NZLDD). The database includes...
Increased globalization of food trade has dramatically increased "food miles," the distance travels. The impacts miles on environment, biodiversity, security, and farmers' livelihoods are garnering increasing attention, but market forces affecting a lessening little studied. This project examined previous literature; direct, local fresh produce operations; producer insights to develop recommendations for locally produced food. Producer size, product perishability, proximity population...
Evaluating the influence of earthquakes on erosion, landscape evolution and sediment-related hazards requires quantifying volume velocity post-seismic sediment cascades. However, accurate estimates post-earthquake transfers remain rare. Following 2016 MW7.8 Kaikōura earthquake in New Zealand, erosion was quantified directly by measuring ground surface change between 4 lidar surveys captured 2016, 2017, 2019 2021 using multiscale model-to-model cloud comparison (M3C2) algorithm. The...
Large earthquakes play a major role in the topographic evolution of active orogens. Earthquake induced landslides can alter mass balance mountain belts for decades to centuries depending on how landslide material is transported and stored.

This study provides the first New Zealand-wide assessment of hydrocarbon seal rock potential twenty sedimentary basins and is designed to help evaluate pre-drill risk assessment. Seal quality has been assessed using key petroleum wells seismic lines. Deep-sea drilling research holes provide glimpses stratigraphy in some more distal basins. The Taranaki Basin currently Zealand's only producing basin — all others are frontier many have no or few exploration rather sparse coverage. We produced...
