Significant Earthquakes and Faults
Fault Name Index
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
Interval Between Major Ruptures: unknown
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.
