(?) Unit Thickness Unnamed (QTp): Coastal floodplain deposits, including channelized fluvial (Paso Robles Fm?) and deltaic deposits. Morphology varies from incised

to braided to meandering style across survey area.

Lower unit characterized by stratified deltaic and/or

nearshore deposits. Interfingers with marine shelf

deposits onshore. Holocene (Qs): Holocene marine shelf deposits. Stratified sand, slits, and clay. Franciscan Complex (KJf): Chaotic, unstratified assemblage of varying lithologies, including fine-grained metavolcanic rocks (with

strong magnetic resistivity values), sheared

claystone (melange matrix), glaucophane schist, and chert. Serpentine is included in the

Franciscan Complex. Regionally, graywacke

sandstone is a prominent component of the

Franciscan Complex but is not common within

the mapped area described in this report. Cretaceous Sandstone (Ks): Well-bedded brown fine- to coarse-grained sandstone, moderately to very well lithified, generally quartz

grains with minor feldspar and lithic grains. Also

includes yellowish brown to black fissile shale, and dark brown fine- to medium-grained

unstratified vesicular basalt and diabase. Abuts

Franciscan Complex rock along faulted contacts. Obispo Formation (Tmo): Resistant sub-unit (Tmor) is crudely bedded to unstratified, orange-brown to gray fine-grained zeolitized tuff, very well lithified, chaotic, unstratified intervals

with basal scour and rare intervals of black silty

sandstone. Fine-grained sub-unit (Tmof) is

well-bedded light brown to gray sandstone and

silty sandstone, coarsening gradually up-section, including abundant invervals of dolomitic

sandstone and common intervals of diatoma-

ceous and tuffaceous sandstones. Diabase

sub-unit (Tmod) is brown aphanitic to phaneritic

intrusive dikes and sills. Tuffaceous sub-unit (Tmot) is grouped with Tmor sub-unit along the

coastline at DCPP but is mapped by Hall (1973a;

1973b) elsewhere in San Luis Obispo County.

Basal contact with Rincon Formation is not

exposed along coastline but is mapped as

conformable in the Irish Hills by Hall (1973a).

Contact with basement rock along coastline may

be depositional, intrusive, or faulted.

Channel A has a preferred slip rate of 0.01 mm/yr (range: 0.0007 to 0.04 mm/yr), Channels B and F have a preferred slip rate of 0.1 mm/yr (range: 0.0007 to 0.3 mm/yr), Channel C has a preferred slip rate of 0.05 mm/yr (range: 0.0007 to 0.15 mm/yr), and Channels D and E have a preferred slip rate of 0.1 mm/yr (range: 0.00007 to 0.2 mm/yr).CUMULATIVE OFFSET (m) 1 101001,00010,0001,00010,000100,0001,000,00010,000,000OFFSET AGE (Yrs) Oceano Fault Zone Slip Rates 1 mm/y0.1 mm/y0.01 mm/yr Channel A Channel AChannels B and FChannel CChannels D and EPacificGasandElectricCompanyFigure OFFSHORE LESS STUDIES 8-3 File path: N:\Projects\04_2013\04_7922_4500_PGESeismicDataInterpretation\Outputs\2013_09_30_PGESeismicDataInterpRev1\ai\Figure_ 7-9A_SF_OF_Slip.ai; Date: 07/23/2014; User: Bryan Bergkamp, Fugro; Rev.0 Oceano Fault Zone Slip Rates Ch3.GEO.DCPP.TR.14.02 R0 Pacific Gas and Electric CompanyFigure(((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((^ _Santa Barbara M w 5.11978San Simeon M w 6.52003Parkfield M w 6.02004Point Sal M w 5.11980Hosgri fault zoneSan Juan faultRinconada faultNorth Channel Slope faultLa Panza faultSouth Cuyama faultEast Huasna faultLos Osos faultLions Head faultSanta Ynez (West) faultLost Hills faultOceanic - West Huasna faultSanta Ynez River faultCasmalia faultSan Andreas faultLittle Pine faultMorales faultPitas Point faultShoreline fault zoneSMR faultOceano faultLos Alamos faultWilmar Avenue faultMorales fault eastBig Pine fault westGreat Valley faultSouth Branch Santa Ynez faultLos Berros faultPurisima StructureLompoc StructureSan LuisObispo BayfaultHosgri fault zoneRinconada faultOceano-SMR fault DCPP-119°39'-119°39'-119°59'-119°59'-120°19'-120°19'-120°39'-120°39'-120°59'-120°59'36°0'36°0'35°40'35°40'35°20'35°20'35°0'35°0'34°40'34°40'34°20'34°20'Figure extentGeneralized Fault Activity and Seismicity MapOFFSHORE LESS STUDIES 9-13D LESS extentsEXPLANATION> 5 mm/yr1-5 mm/yr< 1 mm/yrSlip Rate CategoriesFaultsStrike-slip fault (dips 70 o to 90 o)((((Reverse of thrust fault, teeth on hanging wall(dips 30 o to 75 o)((((Reverse or thrust fault, mostly blindOblique-slip fault, reverse component(dips 45 o to 75 o)((((Fault poorly characterizedOffshore AnticlineFile Path: N:\Projects\04_2013\04_7922_4500_PGESeismicDataInterpretation\Outputs\2014_04_20_LESSStudiesRev3\mxd\Figure_9-1_FaultActivitySeismicity.mxd; Date: 7/17/2014; User: Robert Dame, Fugro; Rev.3Earthquake Epicenter M w1.5 - 2.93.0 - 3.94.0 - 4.95.0 - 5.96.0 - 6.9+/-Map projection and scale: WGS 84 / UTM Zone 10N, 1:600,000 0102 0mi.0153 0 kmNotes:1) SMR = Santa Maria River.2) Faults modified from UCERF3, Department of Water Resources (2002), PG&E (2013), Dibblee (1966, 1986), and this study.
