Description :
On the west coast of Vancouver Island, in the Brooks Peninsula, 201 debris slides and debris flows were identified and characterized on aerial photographs, and then mapped and transferred to a GIS for analysis. Based on detailed landslide surveys, the AA. propose a new method to accurately determine volume of landslides of this type by measured total area. With the magnitude-frequency relationships of the data set they present a strong argument that the rollover effect is not merely an artefact, but is instead a consequence of the physical characteristics of the landslides themselves.
