苏格兰几乎所有记录在案的滑坡都属于以下四种类型之一：非旋转岩质边坡破坏（主要的岩崩、平移滑动、倾覆或凹陷，通常是某种组合）；旋转岩质边坡破坏；泥石流;以及漂流或风化层中的平移幻灯片。非旋转岩坡破坏在高地变质岩，尤其是片岩，以及赫布里底群岛和米德兰河谷的火成岩陡坡上尤为常见；旋转岩质边坡破坏几乎总是发生在被抗性火成岩覆盖的弱沉积岩中；泥石流最常见于沙流或风化层。以前的冰川活动对确定滑坡分布也很重要。绝大多数岩质边坡的破坏都是古老的特征，但泥石流和小的漂移滑动（两者都主要由强暴雨引起）现在更频繁，造成更大的破坏，特别是对交通的破坏。
Abstract Almost all documented landslides in Scotland belong to one of four categories: non‐rotational rock slope failures (major rockfalls, translational slides, topples or sags, often in some combination); rotational rock slope failures; debris flows; and translational slides in drift or regolith. Non‐rotational rock slope failures are particularly common on Highland metamorphic rocks, especially schists, and on igneous scarps in the Hebrides and Midland Valley; rotational rock slope failures almost invariably occur in weak sedimentary rocks overlain by resistant igneous rocks; and debris flows are most common on sandy drift or regolith. Former glacial activity has also been of importance in determining landslide distribution. The great majority of rock slope failures are ancient features, but debris flows and small translational slides in drift (both triggered mainly by intensive rainstorms) are much more frequent at present and cause much greater damage, particularly to communications.
