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 Coseismic landslides are observed in higher concentrations around surface-rupturing faults. This observation has been attributed to a combination of stronger ground motions and increased rock mass damage closer Past work shown it is difficult separate the influences from strong on landslide occurrence. We measured coseismic off-fault deformation (OFD) zone widths (treating them as proxy for areas more intense damage) using high-resolution, three-dimensional surface displacements...
Abstract. Modeling suggests that steep coastal regions will experience increasingly rapid erosion related to climate-change-induced sea level rise. Earthquakes can also cause intense episodes of cliff retreat, but coseismic failures are rarely captured in the historical record used calibrate most retreat forecast models. Here, we disaggregate cliff-top strong ground motion and non-seismic sources, providing a unique window into earthquake contributions multidecadal retreat. Widespread...
Abstract. Coastal hillslopes often host higher concentrations of earthquake-induced landslides than those further inland, but few studies have investigated the reasons for this occurrence. As a result, it is unclear if regional landslide susceptibility models trained primarily on inland are effective predictors coastal susceptibility. The 2016 Mw 7.8 Kaikōura earthquake northeastern South Island New Zealand resulted in ca. 1600 > 50 m2 slopes 15∘ within 1 km coast, contributing to an...
Abstract Tectonic deformation within fault damage zones can influence slope stability and landslide failure mechanisms due to rock mass strength effects the presence of tectonic structures. Here, we used detailed site investigations evaluate controls on Half Moon Bay complex, located ~1 km from surface trace Hope in South Island New Zealand. During 2016 Mw 7.8 Kaikōura earthquake, experienced up ~13 m displacement partially transitioned into a avalanche (with volume ~350,000 m3). Deep-seated...
Abstract. Coastal hillslopes often host higher concentrations of earthquake induced landslides than those further inland, but few studies have investigated the reasons for this occurrence. As a result, it remains largely unclear if regional landslide susceptibility models trained primarily on inland are effective predictors coastal susceptibility. The 2016 Mw 7.8 Kaikōura northeast South Island New Zealand resulted in c. 1,600 > 50 m2 slopes 15° within 1 km coast. This forms an order...
The 2016 Mw 7.8 Kaikōura earthquake on New Zealand’s South Island triggered c. 30,000 landslides. Around 70% of landslides occurred in Torlesse greywacke rock mass, which is characterised by closely spaced but low-persistence joints. Most failures this mass were relatively shallow avalanches do not appear to follow traditional failure mechanism models. Here, we use detailed site characterisation and dynamic numerical modelling better understand landslide hazard risk from...
Strong ground motion intensity measures, for example Peak Ground Acceleration (PGA) or Velocity (PGV), are important dynamic features, predictive variables, in most regional earthquake induced landslide susceptibility models. Despite global reliance on these little work has been done to evaluate how feature selection, and underlying models, influence the performance of Here, we conduct a sensitivity analysis, training suite 131 comparative logistic regression models distribution landslides...
Landslide hazard is, in part, dependent on failure mechanism and stage of the slope. Hazard can increase for same slope when it transitions from incipient to sliding avalanching. Many regional-scale coseismic displacement-based susceptibility models require displacement thresholds relate their predicted permanent displacements likely landslide occurrence. In many studies, a fixed threshold is adopted. However, such tend not consider scale or mechanisms displacement. Understanding that lead...
