Mass wasting, also known as mass movement, [1] ... 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. The creep makes trees and shrubs curve to maintain their ...

Mass-wasting movement ranges from slow to dangerously rapid. Areas with steep topography and rapid rainfall, such as the California coast, Rocky Mountain Region, and Pacific Northwest, are particularly susceptible to hazardous mass-wasting events. By examining examples and lessons learned from famous mass-wasting events, scientists have a ...

Typically very slow (mm/y to cm/y), but some can be faster: Rock avalanche: A large rock body that slides and then breaks into small fragments: Flow (at high speeds, the mass of rock fragments is suspended on a cushion of air) Very fast (>10s m/s) Creep or solifluction: Soil or other overburden; in some cases, mixed with ice

Movement by mass wasting can be slow or rapid. Rapid movement can be dangerous, as is often the case during debris flows. Areas with steep topography and rapid rainfall, such as the California coast, Rocky Mountain Region, and Pacific Northwest, are particularly susceptible to hazardous mass-wasting events. 10.1 Slope Strength

Creep - the very slow, usually continuous movement of regolith down slope. Creep occurs on almost all slopes, but the rates vary. Evidence for creep is often seen in bent trees, offsets in roads and fences, and inclined utility poles. ... Subaqueous Mass Movements. Mass wasting processes also occur on steep slopes in the ocean basins. A slope ...

11.2 Classification of Mass Wasting ... The very slow—millimeters per year to centimeters per year—movement of soil or other unconsolidated material on a slope is known as creep. Creep, which normally only affects the upper several centimeters of loose material, is typically a type of very slow flow, but in some cases, sliding may take ...

Debris flows are defined as mass‐wasting events in which turbulence occurs throughout the mass. Varieties of these are called earthflows, mudflows, and debris avalanches. ... Earthflows can be fast (a few hours) or slow (a few months). Velocities range from 1 millimeter per day to meters per day. Intermittent activity can continue for years ...

However other mass wasting processes such as slow creep, flow, and subsidence are volumetrically important and merit further attention. Surficial creep, for example, is commonly attributed to the effects of (1) freezing of rock material, (2) expansion perpendicular to a slope, and (3) thawing and contraction, or subsidence with downslope ...

Types of Mass Wasting. Mass wasting processes are classified based on the type of movement, the characteristics of the material involved, and the environmental conditions that influence their occurrence. Some of the common types of mass wasting include: 1. Creep. Creep is a slow, gradual movement of soil and sediment downslope over time.
