Numerical investigation of casing shear deformation due to fracture/fault slip during hydraulic fracturing

open access: yesEnergy Science & Engineering, 2020
The frequent occurrence of casing failure has significantly affected the development of shale gas in the Sichuan Basin. Based on engineering and geology analyses, natural fracture/fault slip leads to casing shear deformation during hydraulic fracturing ...

Deformation due to the 17 August 1999 Izmit, Turkey, earthquake measured from SPOT images [PDF]

open access: yes, 2002
The geometry of the ruptured areas and the coseismic slip distribution data are key to highlighting the behavior of seismic faults. This information is generally retrieved from field investigations and geodetic measurements or synthetic aperture radar ...

Numerical Investigation on the Dynamic Response of Fault-Crossing Tunnels under Strike-Slip Fault Creep-Slip and Subsequent Seismic Shaking

open access: yesBuildings, 2023
Tunnels built in geologically active areas are prone to severe damage due to fault dislocation and subsequent earthquakes. Using the Ngong tunnel in the East African Rift Valley as an example, the dynamic response of a fault-crossing tunnel and the ...

Spectral-element simulations of long-term fault slip: Effect of low-rigidity layers on earthquake-cycle dynamics [PDF]

open access: yes, 2011
We develop a spectral element method for the simulation of long-term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.

Quantitative Constraints on Faulting and Fault Slip Rates in the Northern Main Ethiopian Rift

open access: yesTectonics, 2020
The Boset magmatic segment (BMS) of the northern Main Ethiopian Rift (MER) is an ideal natural laboratory to investigate the kinematics, interaction, and rates of activity within a fault network in a magma‐rich rift.

Rapid fault healing after seismic slip

open access: yesJournal of Geophysical Research: Solid Earth, 2023
Fault strength recovery (healing) following an earthquake is a key process in controlling the recurrence of future events; however, the rates and mechanisms of fault healing are poorly constrained. Here, by performing high-velocity friction experiments at seismic slip rates (0.57 m/s), we show that granite and gabbro fault gouges recover their strength

A Crustal Deformation Pattern on the Northeastern Margin of the Tibetan Plateau Derived from GPS Observations

open access: yesRemote Sensing, 2023
The northeastern margin is a natural experimental field for studying crustal extrusion and expansion mechanisms. The accurate crustal deformation pattern is a key point in the analysis of regional deformation mechanisms and seismic hazard research and ...

Characterization parameters of the evolution degree of strike-slip faults

open access: yesShiyou shiyan dizhi, 2023
Strike-slip faults and their related structures have great value for oil and gas exploration. Accurate understanding of the evolution degree of strike-slip faults is crucial to oil and gas exploration in strike-slip structural belts.

Geomorphic signal of active faulting at the northern edge of Lut Block. Insights on the kinematic scenario of Central Iran [PDF]

open access: yes, 2016
Recent works documented Neogene to Quaternary dextral strike-slip tectonics along the Kuh-e-Sarhangi and Kuh-e-Faghan intraplate strike-slip faults at the northern edge of the Lut Block of Central Iran, previously thought to be dominated by sinistral ...

The Spectrum of Fault Slip in Elastoplastic Fault Zones

open access: yesEarth and Planetary Science Letters, 2023
Natural faults are typically surrounded by damage zones that exhibit inelastic material response. This study investigates the role of fault zone strength in modulating the spectrum of fault slip across different spatio-temporal scales. We carry out long-term simulations of seismic and aseismic slip for an elastoplastic spring slider model with rate-and-
