THE PENNSYLVANIA STATE UNIVERISTY DEPARTMENT OF GEOSCIENCES Estimating the Pleistocene Slip Rate of the Owens Valley Fault, California
Slip rates of the right-lateral Owens Valley Fault lie at the center of an ongoing debate over the rheology and mechanics of lithospheric deformation in eastern California. Slip rates determined from paleoseismic records of surface rupture yield Late Pleistocene – Holocene rates of < 1mm/yr to ~2 mm/yr. The decadal velocity field across the valley, however, approaches ~6 mm/yr of right-lateral ...
متن کاملSlip-Parallel Seismic Lineations on the Northern Hayward Fault, California
A high-resolution relative earthquake location procedure is used to image the fine-scale seismicity structure of the northern Hayward fault, California. The seismicity defines a narrow, near-vertical fault zone containing horizontal alignments of hypocenters extending along the fault zone. The lineations persist over the 15-year observation interval, implying the localization of conditions on t...
متن کاملHolocene slip rates along the Owens Valley fault, California: Implications for the recent evolution of the Eastern California Shear Zone
One of the largest historical earthquakes in California occurred in 1872 along the Owens Valley fault located along the western margin of the Eastern California Shear Zone. New paleoseismic and optically stimulated luminescence data are the first to bracket the timing of the pre-1872 rupture to between 3.3 6 0.3 and 3.8 6 0.3 ka. These data yield an earthquake recurrence interval between 4100 a...
متن کاملStratigraphic record of Pleistocene initiation and slip on the Coyote Creek fault, Lower Coyote Creek, southern California
The Coyote Creek fault is a major strand of the San Jacinto fault zone in southern California. Pleistocene sediments and sedimentary rocks exposed in the lower Coyote Creek area preserve a record of surface deformation, stream reorganization, and erosion that resulted from initiation and slip on the Coyote Badlands strand of the Coyote Creek fault. A well-exposed section of conglomerate and san...
متن کاملKinematics of the Eastern California shear zone: Evidence for slip transfer from Owens and Saline Valley fault zones to Fish Lake Valley fault zone
Late Quaternary slip rates and satellite-based geodetic data for the western Great Basin constrain regional fault-slip distribution and evolution. The geologic slip rate on the Fish Lake Valley fault zone (the northwest extension of the Furnace Creek fault zone) increases northward from about 3 to 5 mm/yr, in agreement with modeled geodetic data. The increase coincides with the intersections of...
