Fault Name Index

Big Pine Fault

Type of Faulting: left-lateral strike-slip
Length: 70 km
Nearby Communities: Frazier Park
Most Recent Rupture: Late Quaternary east of intersection with Pine Mountain fault; Pre-Quaternary west of same intersection
Slip Rate: 1 to 4 mm/yr (?)
Probable Magnitudes: uncertain
Other Notes: Rupture reported in 1852 is thought unlikely (probably landslides). Rupture in Holocene time is possible, but unknown. Slip rate may currently be much less than the 1 to 4 mm/yr average Quaternary rate. The dip is steep and to the south.
