Landslide Occurrence Following Major Rain Storms on Vancouver Island

In November 2006, two large rainfall storm events, occurring two weeks apart, caused major damage to roads, bridges, forests and streams across southern Vancouver Island. These storm events delivered extremely high rainfall and associated high winds, causing hundreds of landslides on Vancouver Island with many occurring in the Bamfield-Port Alberni area.

In this investigation, the Board set out to analyze the landslide activity that occurred in the two years prior and the year following these two large rainfall storm events.
