“…Finally, advanced InSAR processing such as PSInSAR has rendered an improved accuracy in mapping and characterisation of various natural hazards (e.g. Colesanti et al 2003, Hilley et al 2004, Lanari et al 2004, Farina et al 2006, Funning et al 2007, Bell et al 2008, Novali et al 2008, Puglisi et al 2008, Bianchi, 2009). …”

“…In addition, recent satellite-based permanent scatterer interferometric synthetic aperture radar (PS-InSAR) studies (Funning et al, 2007) suggest that to the northwest and southeast of the Santa Rosa pull-apart basin, the Rodgers Creek fault zone is undergoing as much as 7.5 ± 2.6 mm/yr of shallow creep above a depth of 6 km.…”

Evolution of the Rodgers Creek-Maacama right-lateral fault system and associated basins east of the northward-migrating Mendocino Triple Junction, northern California

The Rodgers Creek-Maacama fault system in the northern California Coast Ranges (United States) takes up substantial rightlateral motion within the wide transform boundary between the Pacifi c and NorthAmerican plates, over a slab window that has opened northward beneath the Coast Ranges. The fault system evolved in several right steps and splays preceded and accompanied by extension, volcanism, and strikeslip basin development. Fault and basin geometries have changed with time, in places with younger basins and faults overprinting older structures. Along-strike and successional changes in fault and basin geometry at the southern end of the fault system probably are adjustments to frequent fault zone re organizations in response to Mendocino Triple Junction migration and northward transit of a major releasing bend in the northern San Andreas fault.The earliest Rodgers Creek fault zone displacement is interpreted to have occurred ca. 7 Ma along extensional basin-forming faults that splayed northwest from a westnorthwest proto-Hayward fault zone, opening a transtensional basin west of Santa Rosa. After ca. 5 Ma, the early transtensional basin was compressed and extensional faults were reactivated as thrusts that uplifted the northeast side of the basin. After ca. 2.78 Ma, the Rodgers Creek fault zone again splayed from the earlier extensional and thrust faults to steeper dipping faults with more northnorthwest orientations. In conjunction with the changes in orientation and slip mode, the Rodgers Creek fault zone dextral slip rate increased from ~2-4 mm/yr 7-3 Ma, to 5-8 mm/yr after 3 Ma.The Maacama fault zone is shown from several data sets to have initiated ca. 3.2 Ma and has slipped right-laterally at ~5-8 mm/yr since its initiation. The initial Maacama fault zone splayed northeastward from the south end of the Rodgers Creek fault zone, accompanied by the opening of several strike-slip basins, some of which were later uplifted and compressed during late-stage fault zone re organi zation. The Santa Rosa pull-apart basin formed ca. 1 Ma, during the reorganization of the right stepover geometry of the Rodgers Creek-Maacama fault system, when the maturely evolved overlapping geometry of the northern Rodgers Creek and Maacama fault zones was overprinted by a less evolved, non-overlapping stepover geometry.The Rodgers Creek-Maacama fault system has contributed at least 44-53 km of right-lateral displacement to the East Bay fault system south of San Pablo Bay since 7 Ma, at a minimum rate of 6.1-7.8 mm/yr.

“…The West Napa fault previously experienced an M 5 strike-slip event in 2000 but otherwise exhibited no previous definitive evidence of historic earthquake rupture (Rodgers et al, 2008;Wesling and Hanson, 2008). Evans et al (2012) found slip rates of ∼9:5 mm=yr along the West Napa fault, with most slip rate models for the Bay area placing higher slip rates and greater earthquake potential on the Rodger's Creek and Green Valley faults, respectively (e.g., Savage et al, 1999;d'Alessio et al, 2005;Funning et al, 2007).…”
