ABSTRACT Chemically distinctive features such as high salinity, low nutrient contents, and extremes of pH can limit the development of a vegetation cover on soil‐free bare ground. This study synthesises our previous work on the geoecology of numerous chemically distinctive bare sites in the South Island and adds a temporal component within the last ...

ABSTRACT We combine previous studies, fieldwork, lidar data, and trenching to examine late Quaternary activity of the SE‐dipping ≥23 km long Settlement Fault in the southeastern South Island. Trenching of a scarp crossing a small alluvial fan exposed a > 3 m thick sequence of folded sandy to silty fan alluvium.

Landslides triggered by the December 2021 Eastern Bays storm, Banks Peninsula, New Zealand
ABSTRACT On 16 December 2021, the Eastern Bays region of Banks Peninsula, Canterbury, was affected by a high intensity rainfall event which triggered >1300 landslides. Landslides triggered by the event caused widespread damage to agricultural land and infrastructure, which cut off road access to several communities.

ABSTRACT Loess is a patchy but widespread constituent of East and Central Otago (South Island, New Zealand), where it attests to extensive aerial mobilisation and deposition of fine‐grained sediment. While most Otago loess deposits formed in the Pleistocene, we examine massive, fine‐grained but clay‐altered, Pliocene beds in Central Otago that may be ...

Earthquakes, extreme rainfall, and other conditions can trigger numerous shallow landslides, posing significant safety hazards. Non-obvious landslides, which lack clear precursory signs, are particularly challenging to predict.

ABSTRACT International research on disturbed landscapes has shown that active erosion of soil‐free bare ground can maintain distinctive local geological features and biodiversity by preventing incursion of a robust vegetation cover. In this study, we have tested this approach by removing exotic vegetation and associated proto‐soil that had encroached ...

Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia
ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...

Suspended Sediment Rating Curves for Heterogeneous Karst Watersheds
Abstract Water‐sediment relationships are complicated in karst areas of southwest China due to regional extreme climate, special geological conditions, shallow soil layer, heterogeneous geomorphology and landscape. However, the relative influence of climate, lithology, soil, topography and landscape on sediment‐water relationships in heterogeneous ...

Landslides in the northern Taihang Mountains are concentrated at elevations of 800–1300 m, on slopes over 45°, and in north‐ and northwest‐facing aspects. Proximity to rivers increases landslide frequency, whereas faults influence landslide size. Loess deposits, grasslands and forests exhibit high landslide occurrence, with barrens showing the densest ...
