Hapuku landslide dam changes, 2016 to 2019

Surface change models of the Hapuku landslide dam have been generated using Light Detection And Ranging (LiDAR) surveys between 2016-2017, 2017-2018 and 2018-2019. The colours in the two epoch pairs shown below depict areas of erosion (reds to yellows) and deposition (greens to blues). Changes between the surveys can be seen using the slider in […]

The Kaiwhata landslide dam

Not all landslide dams are formed by earthquakes, but any landslide dam can be used to find out more about how long they stay in the landscape and what hazards they may pose. The landslide itself can impact people and property, but when the debris blocks streams and rivers, the dam and impounded reservoir can […]

Earthquake damage to the Hutton’s Shearwater nesting colonies, Seaward Kaikōura range.

People were not the only living creatures affected by the 2016 Kaikōura earthquake. The Hutton’s shearwater or Kaikōura tītī (Puffinus huttoni) is an endangered seabird endemic to the Kaikōura region that nests between 1200-1800 m above sea level in the Seaward Kaikōura Range. These areas are generally only accessible by helicopter. The birds were once […]

Landslide Field Mapping

By Katie Jones, PhD Student in Theme 5: Post-earthquake sediment cascades Together with Chris Massey and Regine Morgenstern, along with fellow PhD students Caleb Gasston and Colin Bloom, we spent 2 weeks in the field during October 2019 and January 2020 visiting a selection of large landslides triggered by the Mw 7.8 Kaikōura earthquake. Unsurprisingly […]

What is a landslide dam?

Landslide dams include any blockage of a watercourse (stream, river, etc.) caused by the movement of material downslope. Often, but not always, the landslides are triggered by large earthquakes, such as occurred during the Kaikoura 2016 earthquake. Many dams are slowly eroded by seepage through the dam or cut down after overtopping by the lake […]
