abstract Slippage (also called creep) on the Hayward fault has produced a right-lateral shift of about 0.7 feet in three sets of railroad tracks that were built 55 and 56 years ago. The average annual rate of 0.15 inch per year is about one-third the average rate of slippage on the San Andreas fault, but the rate has been much greater during short intervals. The zone of acute deformation of the tracks is 20 to 80 feet wide; the tracks are underlain by unconsolidated deposits more than 300 feet thick. Surface faulting at this locality in the 1868, and probably in the 1836, earthquake suggests that the processes of fault rupture and fault slippage can alternate at the same locality.

Surface Breakage

Abstract The Landers, California, earthquake (Mw = 7.3) provides an exceptional opportunity to study surface rupture of an earthquake fault. Detailed maps of the lateral distribution of fracturing adjacent to main traces show that rupture patterns are much more complex than documented in past studies of surface ruptures. The rupture occurs in tabular zones, up to hundreds of meters wide. A main trace within each rupture zone accommodates much of the shear deformation, but considerable fracturing occurs throughout the tabular zone. The en-echelon pattern of fracturing in step-over zones between main traces is typically even more complex than those along major fault zones. Inspection of several on-grade concrete slabs indicates that unreinforced concrete foundations generally crack when subjected to distinct ground ruptures beneath them or when they are twisted because of differential ground movements across broad zones. Methods of mitigating the potential hazards associated with earthquake fault rupture are presented.
