When a landslide dams a river, what is the ultimate hazard?

• Lack of water supply downstream making municipalities struggle to operate

• Rising lakewater makes mud and causes even more mudflows and debris flows

• The dam forms a rising lake that may overtop the dam, washing it out, and causing deadly flooding downstream

• Toxic minerals from fresh rocks and soils exposed by the landslide contaminate the lake and surrounding area

• Water from the river saturates the surrounding area causing more landslides

• talus blocks

• nearby cliff (with crescent shapes indicating scarp)

• nearby stream
