What Is an Earthquake?: Scarp Formation
This is a short lesson about scarp formation. The answer is provided as an animated GIF. This example points out a general rule of fault-related geology: the apparent offset of a feature (in this case, level ground offset vertically) is not always an indication of the actual displacement (horizontal cutting of a pre-existing scarp) along a fault. This is one of the more extreme examples of that rule.
