When the factor of safety is less than one, driving forces are greater than resisting forces, and failure will occur. Geologija 51 2: Large-scale heterogeneities often control the initiation and location of failure.
- The vibration from an earthquake can cause liquefaction in uniformly graded, fine-grained, sediments due to loss of effective stress.

- Geologija 59 2:
- Vegetation generally serves to stabilize a slope; the roots of plants serve as anchors, and vegetation decreases the water content of a slope.
- Sassa, K.
The failure surface in homogenous soils is sub-spherical, resulting in a rotational slide. Although the observed and measured data should be considered informative due to the simplified methods, the primary purpose to get practice in recognition of landslide elements was achieved. The representation of an earthquake as a single, continuous force on a slope is not accurate.
As magnitude increases, the extent of landsliding increases. Figure is from De Blasio Earthquake triggers Earthquakes cause failure in two different manners.
Figure 3: Triggers A landslide trigger decreases the factor of safety to less than one. All of these factors must be evaluated for each potential slide, and considered when analyzing a slide that has already occurred.

Cohesion values for rock may be s of times larger than those of soils De Blasio, Human induced triggers include removal of the toe of the landslide through excavation, loading of the head of the landslide addition of massand artificial vibration.
Sands and gravels are effectively cohesion-less. In the 4-month period inthe local research proposal library of the cooperative team recorded the distance between pairs of wooden stakes transversely to opened crack on point 1 Fig.

Increasing friction and cohesion increases the strength and therefore increases the factor of safety. Research institutions play a particularly important role in landslide risk reduction, but are not always considered during the course of developing landslide prevention plans.
- Instead of failing along a pre-existing plane of weakness, soils often fail along a sub-spherical shell where the lowest factor of safety occurs.
