1. Introduction More than 20 faults are inferred to have moved in the M7.8 November 2016 Kaikōura Earthquake, which resulted in extensive damage to the coastal slopes and caused uplift at several locations. Between Clarence and Oaro, the transport corridor is located on a narrow…
Introduction The 14 November 2016, M7.8 Kaikōura Earthquake severely damaged the North Canterbury region. The earthquake resulted in significant ground shaking triggering widespread landslides, extensive coastal uplift on multiple faults, and a locally sourced tsunami. The earthquake caused significant damage over a very large area,…
Prepared by sally Dellow and Chris Massey on behalf of the GeoNet Landslide Team and the USGS and GEER reconnaissance teams 1 The November 14, 2016, Mw 7.8 Kaikoura earthquake triggered thousands of landslides over a total area of about 10,000 km2, with the majority…
The North Canterbury Transport Infrastructure Recovery (NCTIR) has been set-up by the government under the Hurunui/Kaikoura Earthquakes Recovery Act 2016. Its purpose is to repair and re-open the earthquake-damaged road and rail networks between Christchurch and Picton by the end of 2017. This includes the…
Above: Mapped fault ruptures as of press time (courtesy GNS Science). Overview of Ground ruptures In the area we have covered a number of faults have ruptured in a complex relay extending from the NW margin of Culverden basin to the NE, toward Kaikoura. The…
NCTIR Geotechnical Team The North Canterbury Transport Infrastructure Recovery (NCTIR) has been set-up by the government under the Hurunui/Kaikoura Earthquakes Recovery Act 2016. Its purpose is to repair and re-open the earthquake-damaged road and rail networks between Christchurch and Picton by the end of 2017….
As we were once again reminded in November 2016, New Zealand is a very dynamic country. Being a country with a relatively small area, such a large earthquake will inevitably affect our infrastructure and a wide variety of intensive and non-intensive land use. This provides…

Abstract Routine effective stress analyses for failure of geotechnical structures use a linear Mohr-Coulomb envelope and routine analyses for ground movements use linear elasticity with constant Young’s Modulus E’ or one-dimensional modulus M’. Observations of soil behaviour show that strength and stiffness are non-linear and…
Abstract The movement of many landslides is controlled by the force imbalance associated with a reduction in shear resistance caused by a decrease in normal effective stress as pore water pressures increase. This basic premise might lead to an assumption that the movement rate has…
