Creep. 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.
Q. What is the type of mass of spread?
e) Spreads: A spread is an extension of a cohesive soil or rock mass combined with a general subsidence of the fractured mass of cohesive material into softer underlying material. The rupture surface is not a surface of intense shear. Spreads may result from liquefaction or flow (and extrusion) of the softer material.

Washington state
Q. What are the 4 resisting forces?
The main driving force in most land movements is gravity. The main resisting force is the material’s shear strength. Slope angle, climate, slope material, and water contribute to the effect of gravity. Mass movement occurs much more frequently on steep slopes than on shallow slopes.
Q. How will you know if there’s going to be a landslide?
Water breaks through the ground surface in new locations. Fences, retaining walls, utility poles, or trees tilt or move. A faint rumbling sound that increases in volume is noticeable as the landslide nears. Unusual sounds, such as trees cracking or boulders knocking together, might indicate moving debris.
Q. Which are the major factors which trigger landslides?
Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
Q. What are the harmful effects of landslides?
The impact of a landslide can be extensive, including loss of life, destruction of infrastructure, damage to land and loss of natural resources. Landslide material can also block rivers and increase the risk of floods.
Q. What is landslide disaster give two examples?
Landslides occur when ground on slopes becomes unstable. The unstable ground collapses and flows down the side of a hill or mountain, and can consist of earth, rocks, mud and any debris which may be caught in its wake. If a landslide occurs near inhabited areas, it can cause a great deal of damage.
