Characteristics and impacts of earthquake-induced landsliding

Doug Mason

The resilience of our built environment to natural disasters such as earthquakes is critical for the community.  New Zealand has rugged terrain, which means that engineered cut and fill slopes are required to form infrastructure, transport routes, residential developments etc., and the high seismicity over much of the country means these slopes are exposed to landslide hazards in earthquakes.   Understanding the common mechanisms of slope failure is important for the design of slopes, so the different factors that influence slope failure and the consequences of the failures can be accounted for in a resilience-based design approach.  This presentation will outline recent earthquake-induced landslides, and discuss factors that are important for understanding the performance and design of slopes.  Observations of slope failures in events such as the 2016 Kaikōura earthquake highlight the importance of understanding structural geological controls on the type and extent of slope failure, as well as the consequent impacts on the built environment.  The widespread effects of landslides triggered by large earthquakes also reinforce the need to consider the susceptibility of slopes to landsliding on a regional scale, to underpin initiatives for managing landslide hazards such as land use planning measures and emergency response planning.
