Compressive and extensive horsetails are common structures on the lateral termination of brittle strike-slip faults, which forms within the shallow continental crust. Here we report another possibility, the lateral termination of a brittle strike-slip fault in a formation-parallel low-temperature ductile shear zone within sulphatic, gypsum-dominated evaporites. In the Southern Alps, over a dist...

The Mw 7.3 1995 Aqaba earthquake is the largest instrumental earthquake along the Dead Sea Fault. We complement previous seismological studies by analyzing co-seismic ground displacement from differential interferometry computed from ERS images spanning 3 different areas. They are compared with a synthetic model derived from seismological study. Only far-field deformation related to the main su...

We show the results of application of Differential SAR Interferometry to the MW 7.4, August 17, 1999, Izmit earthquake, Western Turkey. The differential interferogram is obtained using an interferometric ERS2 ascending pair with a time interval of 35 days (August 13th September 17th). The fringe pattern clearly defines the coseismic displacement field extended in an area of about 100 km N-S and...

[1] Large-scale crustal deformation in the Levant is mainly related to the DST and the CFS. The former is an active left lateral transform, bounding the Arabian plate and the Sinai sub-plate, and the latter branches out of the former and separates the Sinai sub-plate into two tectonic domains. In this study we obtain the velocities of 33 permanent GPS stations and 145 survey stations that were ...

[1] Lateral variations of the crustal structure in southern California are determined from receiver function (RF) studies using data from the Southern California Seismic Network broadband stations and Los Angeles Regional Seismic Experiment surveys. The results include crustal thickness estimates at the stations themselves, and where possible, cross sections are drawn. The large-scale Moho dept...

The buried hills in the Chengdao–Zhuanghai area are rich oil and gas resources, their structures exhibit complex styles with unique evolutionary characteristics. Based on most recent exploration progress this region, structural characteristics active parameters of hill faults region were quantitatively analyzed using balanced section technique. In addition, evolution process study was reproduce...

Geodetic studies have produced different interpretations of the relative vertical thickening versus escape tectonics occurring within the Los Angeles basin based on calculated horizontal strain rates ranging from 56 10 /yr contraction at N36 E to 85 10 /yr north–south contraction and 60 10 /yr east–west extension. Three-dimensional forward mechanical models of faults in the Los Angeles basin ar...

Abstract The Eastern California shear zone is a complex set of dextral faults that accommodates significant plate motion and has produced large earthquakes. evolution this system why it consists closely spaced, irregular fail in multi‐fault ruptures are not well understood. Here we analyze the geometry, spatial distribution, Quaternary slip activity right‐lateral southern Mojave block. We find ...

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...

Estimating and detecting faults is crucial in ensuring safe efficient automated systems. In the presence of disturbances, noise, or varying system dynamics, such estimation even more challenging. To address this challenge, article proposes a novel filter to estimate multiple fault signals for class discrete-time linear parameter-varying (LPV) The design formulated as an optimization problem sol...
