Garnet Hill Fault

TYPE OF FAULTING: right-lateral strike-slip
but evolves into oblique right-reverse at extreme western end
LENGTH: 25 km
NEAREST COMMUNITIES: White Water, North Palm Springs, Palm Springs
MOST RECENT SURFACE RUPTURES: Holocene at western end; otherwise, Late Quaternary
SLIP RATE: estimated at 10 to 20 percent of the slip rate of the Banning fault
PROBABLE MAGNITUDES: MW 6.0 - 7.0, alone; might ruputure along with nearby faults
DIP: The Garnet Hill fault dips to the north.
OTHER NOTES: Displayed ground cracking along surface trace after the 1986 North Palm Springs earthquake. This was not surface rupture, however, but was due to strong shaking.
