... of the Berkeley Hills on the eastern side of campus ( Figure 1 ). Mapping of the Hayward Fault through Berkeley indicates that the fault typically lies along the base of the Berkeley Hills and is characterized by active creep at the ground surface ( Lienkaemper, 1992 ). This mapping also indicates that at least...

Most other M ≥ 4.5 earthquakes occurring within the region prior to 1989 represent thrust/reverse faulting or strike-slip faulting adjacent to the Denali fault system. These results highlight the role thrust faulting plays...
