Sakumaha anu tiasa ditempo dina Gambar 1, éarthen slopes can develop a cut-spherical wéakness zone.  The probability of this happening can be calculated in advance using a simple 2-D circular analysis package. A primary difficulty with analysis is locating the most-probable slip plane for any given situation. Many landslides have only been analyzed after the fact.

Slope stability issues can be seen with almost any walk down a ravine in an urban setting.  An example is shown in Figure 2, where a river is eroding the toe of a slope, and there is a swimming pool néar the top of the slope. If the toe is eroded too far, or the swimming pool begins to léak, the forces driving a slope failure will exceed those resisting failure, and a landslide will develop, possibly quite suddenly.
