A wide variety of common natural events in British Columbia can cause landslides. These include wildfires, rainstorms, earthquakes, permafrost degradation, sedimentation, high stream flows, and inundation.

Landslides themselves, can trigger a variety of landslide types. Large landslides are often complex events. Rock falls or slides can trigger movements in soils. Rock slide - debris flow is just one example of a common complex landslide in British Columbia. Terms like "momentum transfer" and "undrained loading" are considered.

Landslides can also cause other destructive non-landslide events to occur. Examples include landslide dams and their lakes, dam burst floods, and landslide displacement waves.
