A "sackung" (plural sackungen) is a deep-rooted, generally slow-moving slope failure involving large volumes of bedrock.
The presence of existing slope failures was explicitly not included as one of the factors, because knowledge of existing slides renders the creation of a landslide susceptibility in order to delineate areas needing further and more thorough investigation, obsolete.

Another type of slope failure common in this area is an earthflow, which is a downslope surface movement involving a substantial amount of mixing of the surface material (Goudie 1994; Hansen 1995).
Some specific topics examined include multi-hazard analysis in natural risk assessments, the definition of rainfall thresholds for diffuse landslides, and computer analysis of slope failure and landslide processes caused by water.
Other topics include forensic study of a reinforced soil slope failure, mixing and compaction temperatures for modified asphalt mixtures, the effect of de-icing chemicals on crack sealant performance, and recycled aggregate concrete for pavement construction.
Because water is often the common denominator in all these conditions, controlling surface and ground water can prove effective in preventing slope failure in the long term.
As Hong Kong is now a highly urbanized international city, a very minor slope failure (ie the failed soil mass is of a small volume and manifests a small travel distance) leads to considerable economic consequences with possibility of fatalities.

Shenandoah, with its steep mountain terrain, is particularly vulnerable to slope failure and debris flows during severe storms, as illustrated by a June 1995 storm in which about two feet of rain fell in a few hours, causing a mountainside slope in the park to give way, sending trees and boulders the size of houses tumbling downhill.
