The interseismic strain across the Altyn Tagh Fault at 85°E has been measured using 59 interferograms from 26 ERS‐1/2 SAR acquisitions on a single track for the period 1993–2000. Using an atmospheric delay correction that scales linearly with height, we estimate the left‐lateral strike‐slip motion to be 11 ±1σ 5 mm/yr, assuming no relative vertical motion and a 15 km fault locking depth. This is in agreement with sparse GPS measurements. The atmospheric delay corrections agree well with coarse… 

InSAR-Constrained Interseismic Deformation and Potential Seismogenic Asperities on the Altyn Tagh Fault at 91.5-95°E, Northern Tibetan Plateau

Two potential asperities that could be nucleation sites or rupture areas of future earthquakes were delineated based on the coupling coefficient and seismicity distributions along the fault plane and support the undeformed blocks model of the Indo-Eurasian collisional mechanism at the northern margin of the Tibetan plateau.

Rapid strain accumulation on the Ashkabad fault (Turkmenistan) from atmosphere‐corrected InSAR

We have measured interseismic deformation across the Ashkabad strike‐slip fault using 13 Envisat interferograms covering a total effective timespan of ∼30 years. Atmospheric contributions to phase

Interseismic Deformation of the Altyn Tagh Fault Determined by Interferometric Synthetic Aperture Radar (InSAR) Measurements

The results support the dynamic models of Asian deformation requiring low fault slip rate and show that high-resolution 2-D strain rates field can be calculated from InSAR alone, even without GPS data.

Crustal Deformation of the Altyn Tagh Fault Based on GPS

A Fine Velocity and Strain Rate Field of Present-Day Crustal Motion of the Northeastern Tibetan Plateau Inverted Jointly by InSAR and GPS

It is inferred that the middle-lower part of the seismogenic layer on the 1920 rupture is not yet fully locked since the 1920 large earthquake, and the expanding frontier of the northeastern plateau has crossed the Liupan Shan fault zone and arrived at the northeast area of the Xiaoguan Shan.

Nailing down the slip rate of the Altyn Tagh fault

Previous estimates of the geodetic and geologic slip rates of the 1500 km long Altyn Tagh fault bordering the northern edge of the Tibetan plateau vary by a factor of five. Proposed reasons for these

Inescapable slow slip on the Altyn Tagh fault

GPS surveys conducted in 1994, 1998, and 2002 on the central portion of the Altyn Tagh fault confirm left‐lateral slip rates of 9 ± 4 mm/yr, significantly slower than geological estimates of slip

Thin‐plate modeling of interseismic deformation and asymmetry across the Altyn Tagh fault zone

Creeping dislocations in an elastic half‐space are commonly used to model interseismic deformation. However, this semi‐infinite conventional model can lead to biased inferences of the slip rate and
