Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock. Movement is caused by shear stress sufficient to produce permanent deformation, but too small to produce shear failure. ... Continuous, where shear stress continuously exceeds the strength of the material.

What causes creep to occur?
It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material. Creep is more severe in materials that are subjected to heat for long periods and generally increases as they near their melting point. ... Therefore, creep is a "time-dependent" deformation.
How does creep occur mass movement?
Soil creep is a slow and long term mass movement. The combination of small movements of soil or rock in different directions over time is directed by gravity gradually downslope. The steeper the slope, the faster the creep.
What damage does a creep cause?
The damage may include foundation or framing damage, sewer line damage, roof damage, doors and window sticking, garage floor and slab cracks as well as cracks in swimming pools and spas, etc. When your home sits on a lot that has slope creep, the entire home usually moves or shifts, not just one small portion.
What causes Earthflow?
A rapid earth flow typically begins as a small landslide on a steep bank where a stream or river has eroded a valley into a sensitive clay deposit. Excess precipitation, elevated ground-water levels, earthquakes, pile driving and long-term erosion have triggered such earth flows (Sharpe, 1938; Lefebvre, 1996).
What causes creep landslide?
The slowest kind of landslide is known as creep. When clay in the soil on a hillside absorbs water, it will expand, causing the soil to swell. As the clay dries and contracts, the particles settle slightly in the downhill direction. ... As a result, the water and soil move slowly downhill like thick porridge.
Where does creep occur?
Creep is a type of metal deformation that occurs at stresses below the yield strength of a metal, generally at elevated temperatures. One of the most important attributes of any metal is its yield strength because it defines the stress at which metal begins to plastically deform.
What is landsliding explain?
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. ... Almost every landslide has multiple causes.
What is a geology creep?
Creep is the imperceptibly slow, downslope movement of soil and earth materials. Rates of movement are often only a few centimeters per year, but the inevitability of creep can severely impact shallowly-placed structures.
What are three indications that creep is occurring?
Creep is indicated by curved tree trunks, bent fences or retaining walls, tilted poles or fences, and small soil ripples or ridges.
What is the difference between fatigue and creep?
Creep is permanent deformation over time; fatigue is crack propagation over time. Both occur due to applied loads and both can lead to failure. Creep is characterized by looking at the elongation of the sample; fatigue, by elongation of the crack.
What is creep and example?
The definition of a creep is the act of moving slowly or is slang for a scary or odd person who is unpleasant or repulsive. An example of a creep is a hill that is moving very slowly. An example of a creep is a scary, leering old man who always stares at you when you walk by his house.
How fast is soil creep?
4.2 Soil creep
The highest rates were recorded for temperate climates predominantly affecting soil movement in the surface soils down to the first 25 cm with rates of about 0.5–2 mm yr−1 for the temperate maritime zone and generally higher rates for the temperate continental zone of about 2–10 mm yr−1.
What is an Earthflow landslide?
Definition of earthflow
: a landslide consisting of unconsolidated surface material that moves down a slope when saturated with water — compare mudflow.
How do rockslides occur?
A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses en masse and not in individual blocks. ... The rocks tumble downhill, loosening other rocks on their way and smashing everything in their path.
What causes soil creep quizlet?
Soil creep is the very slow movement of soil, about 1cm per year. ... Water and gravity cause the soil to move slowly downhill. This movement is shown on the features of the surface.
What causes the processes of creep and Solifluction?
The process of solifluction is the slow downslope movement of soil due to recurrent freezing and thawing of the ground, and results from frost creep and/or gelifluction (Ballantyne, 2018).
What is creep resistance?
Creep resistance is a term used in materials science that refers to a solid material's ability to resist “creep,” which refers to the tendency of a material to slowly deform over a long period of exposure to high levels of stress.
