The purpose of this pilot study was to develop a methodology to assess risk to life from rockfall (boulder roll). The risk is expressed as the annual individual fatality risk. Rockfall triggered by earthquakes and other mechanisms such as rainfall is considered. The assessment includes an analysis of historic and potential future events. The report explains the field verification process used and the required changes made to the risk zone boundaries. Maps showing four classes of annual individual fatality risk are included in the report for select locations on the Port Hills.
