Parkway Drive Landslide

Landslides are common natural hazards in Utah. They often strike without warning and can be destructive and costly. Common types of landslides in Utah are debris flows, slides, and rockfalls.

Many landslides are associated with rising ground-water levels due to rainfall, snowmelt, and landscape irrigation.

Therefore, landslides in Utah typically move during the months of March, April, and May, although debris flows associated with intense thunderstorm rainfall are common in July.
