Landslide Risk
The Hayward Fault in Oakland, California
[1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
Revere Avenue winds across the fault trace at several points. The ground here was quarried before the houses were built, leaving vertical walls of fractured rock. Rockfalls are unavoidable in a magnitude-7 earthquake. Houses on upper Revere Avenue, visible at top, may also slide downslope.
