The paper is…
Comments and opinions expressed in this article are not necessarily those of Waka Kotahi Slope Assessed Risk Level Course(s) The Waka Kotahi/NZTA ARL slope assessment courses previously detailed in the June and December 2020 Geomechanics News, have been delayed by Covid-19 due to the international…
ABSTRACT The Magnitude (Mw) 7.8 Kaikōura earthquake struck the east coast of the South Island of New Zealand in November 2016, resulting in widespread damage to the slopes along the Kaikōura coast. Many of the subsequent remediation measures relied on rock anchors, and a significant…
Jacobs Ladder – A Case-History of Debris Flow in a Post-Seismic Environment T.R. Justice NCTIR/ENGEO, Christchurch. ABSTRACT An increase in debris flows, and other slope stability events, over the short to medium term following significant seismic events is well recorded in international literature. The 2018…

Abstract Disaster recovery takes place in an abnormal environment. A defining tension exists between the need to rebuild quickly, but with careful deliberation. This tension poses risks for the health and safety of workers involved, at a time when risk levels are higher than normally…
Introduction This paper describes the damage that was caused to the South Bay Marina and Coast Guard Station by the 2016 Kaikōura earthquake, and, the associated impact on the local community and economy. An overview of the “fast track” design and construction process that was…
Abstract This paper outlines key elements and the main findings for seismic design of geotechnical structures, i.e. earth retaining systems as well as natural and man-made slopes, and provides an unabridged roadmap for a streamlined design following the principles of value engineering and performance based…
Abstract At 12.03 am local time on 14th November 2016 (UTC: 11.03 am 13th November 2016) a shallow magnitude 7.8 earthquake, with an epicentre located near Waiau in North Canterbury, struck the North Canterbury and Marlborough regions of NZ. The most visible consequence of the…
