Abstract
Landslides are frequent on the unstable slopes of the Mount Meager volcanic massif in the southern Coast Mountains of British Columbia. We compile data on historic and prehistoric landslides to determine the risk to people involved in recreation, geothermal power development, and forestry in valleys proximal to Mount Meager, and also to residents in the Lillooet River valley at distances up to 75 km from the volcano. Landslides 106-107 m3 in size will have direct impacts in Meager Creek and upper Lillooet River valleys and indirect impacts, including channel aggradation and flooding, at more distant locations. Landslides larger than 107 m3, although relatively rare, may trigger volcanic debris flows that will reach populated areas in the Lillooet River valley, 32-75 km downstream from the source. Without advance warning, the loss of life from such an event could be high.
