  Geodetic data comprised of triangulation, trilateration, and astronomic azimuths observed since late to are used to obtain models of horizontal crustal deformation in California. The three regional models roughly cover the California Coast Ranges from San Francisco Bay northward to the Mendocino Triple Junction and from the Great Valley westward to the Pacific by: 4. Geodetically derived strain from San Francisco Bay to the Mendocino Triple Junction, California. Published Date: Series: (NSAF) stretches from the Mendocino Triple Junction, an area in northern California where three tectonic plates meet, south through the San Francisco Bay area.

Key Words lithospheric structure, San Andreas, Gorda plate s Abstract The migration of the Mendocino triple junction through central and northern California over the past 25–30 million years has.

  South of the Mendocino triple junction, the left edge of the model was assumed to be moving roughly at Pacific plate velocity (39 mm yr −1 N34°W) in the absence of observed values to avoid spurious extrapolations. North of the triple junction the left . Escape the hustle and bustle of the Bay Area and make the unforgettable journey to breathtaking Northern California. When you drive from San Francisco to Mendocino via Highway 1, every twist and turn takes you through the towering forests and above the mighty Pacific Ocean.   The remaining sediments coming into San Francisco Bay are derived from the local San Francisco Bay watersheds ().In recent years, sediments from these local watersheds have become increasingly important as sediment input from former hydraulic mining in the Sierra Nevada foothills has waned, and dam construction, bank hardening and channelization in the Sacramento and San . The Mendocino Fracture Zone is a fracture zone and transform boundary over km ( miles) long, starting off the coast of Cape Mendocino in far northern runs westward from a triple junction with the San Andreas Fault and the Cascadia subduction zone to the southern end of the Gorda continues on west of its junction with the Gorda Ridge, as an inactive remnant.

  In particular, such evidence has been found in northern California [Henstock et al., ], in the San Francisco Bay region [Parsons, ; Parsons and Hart, ], and in southern California [Zhu, ]. Based on this evidence, we feel that models with discrete vertical shear zones (Types 3 and 4) provide the best description of lower. GPS-derived velocities (–) in northwestern California show that processes other than subduction are in part accountable for observed upper-plate contraction north of the Mendocino triple. San Francisco Bay Area. In the reference model (λ = ) and comparison models (λ = , λ = ), slip in the San Francisco Bay Area is partitioned across four to seven closely spaced active faults, with six major faults bounding five rotating blocks in the reference model (Fig. 11). Mendocino triple junction. The observed strain rate field illustrates the transition from predominantly right-lateral shear on the NNW-trending SAF system to east–west compression along the megathrust. The transition occurs near the northern terminations of the Maacama and Bartlett Springs faults and northward through the Little Salmon.
