Erosion, which is especially common near riverbanks and rocky sides. It is the least destructive of landslide phenomena. Forest fires instigate soil erosion and bring about floods, which might lead to landslides. Landslides can be triggered by volcanic eruptions. Between 1279 and 1999, 840 landslides claimed the lives of almost 10,000 persons in Italy. This is further supported by inclusion of the large overturned clast from an older member within the formation.

This type of movement is found in bedding planes made of sedimentary or metamorphic rocks dipping in the direction of slope. The surface constantly reshaping itself and landslides are a major reason they strike wherever the soil is loosened by rain or tugged by gravity. Wood fragment inclusions, and mollusk fossils allow 2 methods of dating to confirm time of deposition. Wildfires cause soil erosion and floods, both of which can result in landslides. In his paper, Sloss observes three major unconformities within the basin that coincide with the eustatic transgressions. But there also have a solutions to prevent the landslides from happens. Shear stresses can be built up within a slope by a number of processes. It allows organisms to colonize the slide locations and grow or survive as a result. Transitional slides consist of a planer or 2 dimensional surface of rupture. Due to these astonishing annual losses, most governments have instituted bodies to deal specifically with landslides. He said that accumulated stress within rock particles causes compression of air in the pore spaces. Weathering is the natural decay of rock that leads to unstable, landslide-prone materials. Directing surface water sources away from the landslides; Draining ground water streams away from the landslides; Minimizing irrigation on the surface of the soil. For example, fires ignited as a result of earthquakes, disruption of electrical power and water service as a result of an earthquake, flood, or hurricane, or flooding caused by a landslide into a lake or river. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and rivers from flowing smoothly and can eventually lead to flooding. This essay talks about the Landslide, its meaning and concept, Causes of Land slide, Effects of Landslide and ways how solve the problem of Land slide. Characteristic of some soil particles like clay to swell and shrink alternatively in wet and dry periods; b. These haphazard development activities and inadequate attention to construction aspects have lead to landsides and consequently property damage and loss of life.
