CANTERBURY EARTHQUAKES 2010/11 PORT HILLS SLOPE STABILITY: LIFE-SAFETY RISK FROM CLIFF COLLAPSE IN THE PORT HILLS (2012)

This report assesses the sensitivity of the rockfall modelling used in Canterbury Earthquakes 2010/11 Port Hills Slope Stability: Pilot study for assessing life-safety risk from rockfalls (boulder roll) and Canterbury Earthquakes 2010/11 Port Hills Slope Stability: Life-safety risk from rockfalls (boulder roll) in the Port Hills. A new set of maps show how the reduction in earthquake activity with time changes the risk zone boundaries. The report includes a range of recommendations including the need for the City Council to consider both the original rockfall modelling results and the results from the sensitivity analysis in its decision making. The rock roll zoning decisions were based on maps associated with this report.
