... to creep in depth within a few hours after the Lushan, Jiuzhaigou, and Jinggu mainshocks. The deep creeps mainly follow a velocity‐strengthening friction mode and decay with an Omori law p ‐value of ∼1. The results suggest that the combination of fault healing and geometry together controls deep fault...

... a frictionally heterogeneous megathrust. Coseismically, the zone above the down-dip limit of the aseismic and seismogenic patches undergoes extension and contraction, respectively, while the strain state shows a switch in polarity from coseismic to interseismic. The down-dip limit of the creeping zone produces...

..., and reproduction in any medium, provided the original work is properly cited. California’s central San Andreas fault (CSAF), between Parkfield to the southeast and San Juan Bautista to the northwest, is a well‐studied fault segment that is distinguished by ongoing and substantial shallow fault creep...

... time, suggesting that the faults were creeping according to the velocity‐strengthening friction law. We inferred that the high hydraulic pressure environment contributed to the fault creep, but the dynamic stress perturbation may have been the main factor affecting the fault creep. The results...

... and clustered seismic swarms to unravel the mechanisms that could be driving them. Seismic swarms are indicators that reflect stress changes in space ( Reasenberg and Simpson, 1992 ), whereas repeating earthquakes can be used to identify fault creep ( Shakibay Senobari and Funning, 2019 ; Uchida and Bürgmann...

... an increase in the seismic activity in the creeping section of the San Andreas fault (SAF) (about ∼30 km northwest of the mainshock epicenter) in the weeks prior to the mainshock. We also observe a decrease in the b ‐value parameter in the Gutenberg–Richter relationship in the creeping section in the weeks...

... and Maacama fault segments where substantial creeping is found throughout the rupture segments. The deepest seismogenic depths along the San Andreas are located around the Cholame and Carrizo segments near the Big Bend with depths of about 23 km. Another deeper seismogenic segment of the San Andreas...

...Kaj M. Johnson; Jessica R. Murray; Crystal Wespestad Abstract Widespread surface creep is observed across a number of active faults included in the United States (US) National Seismic Hazard Model (NSHM). In northern California, creep occurs on the central section of the San Andreas fault, along...

...Dezheng Zhao; Chunyan Qu; Xinjian Shan; Roland Bürgmann; Han Chen; Kathryn Materna Abstract Recent geodetic observations of shallow fault creep have illuminated increasingly complex, time-dependent slip behaviors, including quasi-steady creep and temporary accelerations, termed slow-slip events. We...

..., there are three stability regimes in the system: harmonic oscillations, exponential growth, and cubic growth. By combining the different solution regimes within one earthquake cycle, we observe a wide range of behaviors of this simple system: interseismic oscillatory creep, precursory signals before the main...
