Two examples of earthquake fault zone maps are shown in the figure below. The newer map on the left shows an earthquake fault zone as a semi-transparent yellow polygon.

Faults are more likely to rupture (more ready) where tectonic stress has built up over many years without an earthquake. Conversely, faults are less likely to rupture (less ready) when and where a recent earthquake has occurred. We may not know when the most recent earthquake occurred on most faults in California, but we can assume it was ...There are three main types of faults, based on how adjacent blocks of rock move relative to each other. The San Andreas Fault—made infamous by the 1906 San Francisco earthquake—is a strike-slip fault. This means two fault blocks are moving past each other horizontally. Strike-slip faults tend to occur along the boundaries of plates that are ...

A fault is a three-dimensional surface within the planet that might extend up to the surface or might be completely buried. In contrast, a fault line is where the fault cuts the Earth's surface… if indeed it does. The most prominent faults in each state are usually shown on a state's geologic map as black lines.
