| Slip rate based on assumption that slip carried from Concord-Green Valley system (WGNCEP, 1996). Taylor and Swan (1986) and Swan and Taylor (1991) reported minimum slip rate of 1-2mm/yr for segment at Lk. Pillsbury, based on apparent vertical separation and plunge of slickensides. Aseismic slip factor of 0.5 applied based on factor calculated for Concord-Green Valley fault. |
