In this study, Interferometric Synthetic Aperture Radar (InSAR) was used to determine the seismogenic fault and slip distribution of the 3 July 2015 Pishan earthquake in the Tarim Basin, western China. We obtained a coseismic deformation map from the ascending and descending Sentinel-1A satellite Terrain Observation with Progressive Scans (TOPS) mode and the ascending Advanced Land Observation ...

a doublet of earthquakes with magnitudes of 6.5 and 6.2 in mw scale (global cmt) on 2010 december 20 and 2011 january 27 respectively struck the area that lies between the nehbandan and jiroft fault systems, southeast of iran. these earthquakes occurred in correspondence of the southwestern termination of the kahourak right lateral strike slip fault. the focal mechanisms of both the mainshocks ...

The 1999 Chi-Chi earthquake (MW 7.6) (20 September 1999, 17:47:15.9 UTC) (located at 23.853 N, 120.816 E, and depth of 7.5 km) inflicted severe regional scale damage to Taiwan. The strong-motion wavefield was captured by a dense network of stations (with average station spacing of 5 km), which represents the most complete strong-motion dataset to date to use to study the kinematic source proces...

For large earthquakes occurred at and around plate boundaries, we examined relations between seismic moment M 0 , fault length L, fault width W and average fault slip D, and found the following scaling laws. For interplate strike-slip events, the well-known L-cubed dependence of seismic moment M 0 breaks when L exceeds 30 km, and D and M 0 increase with L as D = L==(L+) and M 0 = WL 2 =(L +), r...

The damaged rock around mature faults forms a zone of low seismic wave 24 velocities, which can perturb important earthquake rupture properties. In particular, waves 25 reflected within the fault zone structure can induce short-duration slip pulses, an apparently 26 predominant earthquake rupture mode. Another known mechanism to generate slip pulses is 27 strong velocity-weakening friction. Her...

During the 2011 magnitude 9 Tohoku-oki earthquake, very large slip occurred on the shallowest part of the subduction megathrust. Quantitative information on the shallow slip is of critical importance to distinguishing between different rupture mechanics and understanding the generation of the ensuing devastating tsunami. However, the magnitude and distribution of the shallow slip are essentiall...

We present an inversion strategy capable of using real-time high-rate GPS data to simultaneously solve for a distributed slip model and fault geometry in real time as a rupture unfolds. We employ Bayesian inference to find the optimal fault geometry and the distribution of possible slip models for that geometry using a simple analytical solution. By adopting an analytical Bayesian approach, we ...

[1] We develop a two-dimensional boundary element earthquake cycle model including deep interseismic creep on vertical strike-slip faults in an elastic lithosphere coupled to a viscoelastic asthenosphere. Uniform slip on the upper part of the fault is prescribed periodically to represent great strike-slip earthquakes. Below the coseismic rupture the fault creeps in response to lithospheric shea...

The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures1–6. The fault system that runs from southern California into Mexico is a simple strike-slip boundary: the west side of California and Mexico moves northwards with respect to the east. However, the Mw 7.2 2010 El Mayor–Cucapah ear...
