术语滑坡是指邻近斜坡的大量岩石、残积土或沉积物的快速位移，其中移动块体的重心向下和向外移动。以一种难以察觉的速度进行的类似运动称为蠕动。典型的滑坡所涉及的质量的速度或多或少地从几乎为零迅速增加到至少每小时1英尺。然后，它再次下降到一个小值。相比之下，典型的蠕变是以每十年不到1英尺的平均速率进行的连续运动。更高的蠕变速率是相当罕见的。
The term landslide refers to a rapid displacement of a mass of rock, residual soil, or sediments adjoining a slope, in which the center of gravity of the moving mass advances in a downward and outward direction. A similar movement proceeding at an imperceptible rate is called creep. The velocity of the masses involved in a typical landslide increases more or less rapidly from almost zero to at least 1 foot per hour. Then it again decreases to a small value. By contrast, typical creep is a continuous movement which proceeds at an average rate of less than 1 foot per decade. Higher rates of creep movements are rather uncommon.
