Some of the
most dramatic examples of fault creep are found in a
residential area north of downtown Hayward.
Photographs taken over thirty years show the offset of
the curb at Rose and Prospect Streets.
1971 - Note the position of the curbs and contact between
the curb and sidewalk.
1974 - Note the red paint overspray.
In 1979, there
was about two centimeters or nearly an inch of creep
movement that has offset the curb.
1985 - The two curbs are barely in contact
and new material is filling the gap with the sidewalk.
1987 - The curbs
are adjacent to one another.
1992 - There is
a small gap between the curbs and fresh paint.
Concrete
fills in between the curb and sidewalk.
1993
2002 - The gap between the curbs has widened.
1974 - A series of tears in the asphalt (en echelon
shears) form where the Hayward fault crosses Rose
Street at Prospect. Note each shear is to the left of
the last one. These are said to be left-stepping.
1974 - The curbs on Sunset and Simon Streets (south of
Rose Street)
also show dramatic bends and offsets locating the trace
of the
Hayward fault. Note bend in curb near the back tire of
the car on
Simon Street.
1991 - At Hotel Street there are spectacular
left-stepping, en echelon shears crossing the street.
1984 - The fault crosses under the corner of this house
on Hotel Street, bending the wall and
warping the door-frame.
