Quick Answer
A fault line is the surface trace of a fracture in Earth’s crust where rocks have moved past each other.
The Full Story
Faults are zones where tectonic stress causes rocks to break and slip. The visible line at the ground surface is called the fault trace or fault line, although many faults are buried. Some faults move suddenly in earthquakes, while others creep slowly over time. Famous faults include California’s San Andreas Fault and Japan’s Median Tectonic Line.
