To keep its size manageable, this map excludes the small Shelter Cove segment at the far north end of the San Andreas fault, where displacement in 1906 was vertical, not horizontal, and fault signs are obscure. Motion on nearly all the faults shown on this map is horizontal (lateral), specifically right-lateral. That is, the west side moves north so that looking across the fault, one always sees the other side move to the right.
San Francisco Bay is in the middle. To the west of the San Andreas is the San Gregorio fault; to the east across the bay is the Hayward fault, which has its own tour, with the Rodgers Creek and Maacama faults to its north. The next line of faults to the east are the Calaveras and, to its north, the West Napa faults. Running north from the east side of Livermore are the Greenville, Concord and Green Valley faults, respectively. All of these are considered part of the plate boundary, the greater San Andreas fault zone. Indeed, there is lateral crustal motion on the far side of the Sierra Nevada that is part of the same tectonic regime.
