Fault Name Index

Stoddard Canyon Fault

Type of Fault: left-lateral strike-slip
Length: 18 km
Nearest Communities: Alta Loma, Lytle Creek
Most Recent Surface Rupture: Quaternary
Other Notes: Also called the South San Antonio fault, this north-dipping fault is one of many in a complex system of branching faults north of the Cucamonga fault zone, none of which appear to have been active in Holocene times. The largest of these is the Icehouse Canyon fault, which branches off to the north of the Stoddard Canyon fault. The Stoddard Canyon fault is probably cut and offset by the San Antonio fault to the west, but the intersection of these two faults is buried, and the exact relation is unclear.
