Spatiotemporal Slip Rate Variations Along Surprise Valley Fault in Relation to Pleistocene Pluvial Lakes
… Lake Surprise since the last glacial maximum. Slip rates vary along strike, assuming a fault dip of 68° with 0.25 ± 0.02 mm/yr in the northern section, 1.07 ± 0.10 mm/yr in the central section, and 0.36 ± 0.04 mm/yr in the southern lake section. Potential field modeling of profiles drawn …

Slip rate of the West Tahoe Fault and the age of glacial deposits near Lake Tahoe, California
… the moraines, gives maximum vertical separation rates of 1.5 ± 0.7 and 0.5 ± 0.1 mm/yr since emplacement of the Tioga and Tahoe moraines respectively. At face value this implies a rapid increase in slip rate with time, but because nowhere else in this region is found evidence for rapid changes in …

QUALITATIVE COMPARISON OF OFFSET SURFACES BETWEEN THE CENTRAL AND EASTERN GARLOCK FAULT
… southern end of Death Valley. Although published slip rates are available along the western and central Garlock Fault segments, little is currently known of the Garlock Fault earthquake history or slip rate farther east. Using LiDAR and satellite imagery, the central and eastern Garlock Fault …

Fault Behavior and Kinematic Evolution of the Eastern California Shear Zone
… wide and complex network of right-lateral strike-slip faults, is not well understood, despite hosting three large (>Mw 7.0) earthquake ruptures in recent decades. The low-net slip faults of the ECSZ (each with <10 km) offer a unique opportunity to assess strain distribution in a developing, …

Kinematic models of interseismic deformation in Southern California
… of interseismic deformation and geologic slip rate estimates in terms of block motions. This method accounts for the effects of block rotations and interseismic strain accumulation from active fults. We find that the San Andreas Fault slips close to Its Holocene rate in the Carrizo Plain …

Paleoseismologic Evidence for Holocene Activity on the Pinto Mountain Fault, Twentynine Palms, California
… the Oasis of Mara suggests two to four meters of slip in the most recent event. Assuming three meters as characteristic displacement and seven events in 13.6 ka yields a Holocene slip rate of 1.59-1.80 mm yr<sup>-1</sup>. This rate greatly improves upon previously reported slip rate estimates …

Surface Offset and Slip Rates for the Winter Rim Fault System in the Summer Lake Basin, Oregon
… ~264° (Crider, 2001). The USGS estimates a slip rate of 0.43 mm/yr, earthquake magnitudes of 6.5-7.19, and recurrence interval of 3.1 ka (Crone et al., 2009). However, these estimates are only based upon ARF and the unfavorably slip-oriented SMF. With high-resolution LiDAR, means to …

Present-day and late Quaternary crustal deformation along the southern Dead Sea Fault System, Jordan
… between short-term crustal deformation rates (decadal time scales) and long-term fault slip rates (Holocene to late Pleistocene time scales). This study investigates fault kinematics along the southern Dead Sea fault using tectonic geodesy and late Quaternary slip estimates. The Dead Sea …

Fault segmentation, fault linkage, and hazards along the Sevier fault, southwestern Utah
… stages of a south-flowing stream. Some slip along the Sevier fault occurred after the first two stages and tilted the deposits. (4) 570 ka basalt is offset ∼3 m. Thus, the young slip rate is 0.018 mm/yr. (5) Mechanical weathering processes or seismicity induced 14 landslides and …

Deformation, erosion and sedimentation in collisional orogens : case studies from eastern Tibet and southwestern China
… around the eastern Himalayan syntaxis and integrates geologic mapping, slip-rate estimates, remote sensing, seismicity and geodesy. Fault slip rates are inferred by modeling the elastic deformation near major faults and the motions of a small number of crustal blocks.

Probing quantum phase slips in superconducting nanowires modified using high bias voltage pulses
Quantum phase slips (QPS) or the macroscopic quantum tunneling (MQT) of a nanowire’s order parameter through an activation energy barrier have remained the subject of intense debate for many years. They are expected to occur at low enough temperature where thermally activated phase slips (TAPS) …
