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...
Nonlinear, effective stress finite-element analyses are used to model earthquake-induced displacements at lateral spread sites near a free face. The numerical consist of 132 models with geometries selected isolate the influence height face, thickness liquefiable layers, sloping ground behind and presence topographic terrace on displacement patterns. Each is analyzed in context how geometric factors maximum horizontal displacement, inland extent displacements, shape profile between face...
High-resolution displacement observations of lateral spreading from optical image correlation are available for the 2011 Christchurch (Mw=6.2), New Zealand, earthquake, and these data were used to provide insights into detailed patterns during earthquake quantitatively evaluate performance existing empirical models spread displacements. The observed displacements revealed important characteristics influencing patterns, including topographic terraces enhancing in large regions between terrace...
Liquefaction-induced lateral spreading during the 2011 Christchurch earthquake in New Zealand was severe and extensive, data regarding displacements associated with provides an excellent opportunity to better understand factors that influence these movements. Horizontal measured from optical satellite imagery subsurface Geotechnical Database (NZGD) were used investigate two distinct spread areas along Avon River Christchurch. These experienced between 0.5 2 m, inland extent of displacement...
Finite-element analyses are used to model earthquake-induced lateral spread sites and evaluate the effects of site geometry ground motion intensity measures (IMs) on computed displacements. The were generated with six different geometries, two densities for liquefiable soils, 38 motions a total 456 analyses. A pore pressure ratio threshold 0.5 was establish criterion liquefaction triggering determine which IMs best able predict from non-triggering in numerical models. Cumulative absolute...
