[1] Spatially averaged, absolute deviatoric stress tensors along the faults ruptured during the 2002 Denali fault earthquake, both before and after the event, are derived, using a new method, from estimates of the orientations of the principal stresses and the stress change associated with the earthquake. Stresses are estimated in three regions along the Denali fault, one of which also includes...

In this paper the ATPG is implemented using C++. This ATPG is based on fault equivalence concept in which the number of faults gets reduced before compaction method. This ATPG uses the line justification and error propagation to find the test vectors for reduced fault set with the aid of controllability and observability. Single stuck at fault model is considered. The programs are developed for...

We use high-resolution Synthetic Aperture Radarand GPS-derived observations of surface displacements to derive the first probabilistic estimates of fault coupling along the creeping section of the San Andreas Fault, in between the terminations of the 1857 and 1906 magnitude 7.9 earthquakes. Using a fully Bayesian approach enables unequaled resolution and allows us to infer a high probability of...

magnetotellurics (mt) is an electromagnetic geophysical method of imaging the earth's subsurface by measuring natural variations of the electrical and magnetic fields at the earth's surface. investigation depth ranges from 300m below ground by recording higher frequencies down to 10,000m or deeper with long-period soundings. research applications include experimentation to further dev...

Abstract The Zheduotang fault (ZDTF) is located in the Kangding section of Xianshuihe zone (XSHF). While ZDTF plays an essential role understanding structural deformation pattern section. Little information known about paleoearthquake offsets and slip behavior ZDTF. It therefore to analyze seismic hazards this area. Using UAV-based photogrammetry, high-resolution satellite images, field observa...

During the great 3 May 1887 Sonoran earthquake (surface rupture end-to-end length: 101.8 km; MW = 7.5±0.3), an array of three north-south striking Basin and Range Province faults (from north to south Pitáycachi, Teras, and Otates) snapped along the western margin of the Sierra Madre Occidental plateau. My detailed fi eld survey of the Teras fault and the 1887 earthquake rupture zone along this ...

[1] The Vienna Basin at the transition between the Alpine and Carpathian belt hosts a number of large Pleistocene sub-basins forming along an active continental scale strike-slip fault (Vienna Basin strike-slip fault). We utilize first-order derivatives from industrial Bouguer gravity data to unravel the impacts of Pleistocene kinematics on the Vienna Basin and to compensate for the lack of nea...

Two-dimensional, numerical models of a linear fault embedded within a linear elastic medium show the generation of off-fault tensile failure that results from inelastic slip along the fault. We explore quasistatic models with slip-weakening friction to assess the effects of spatially and temporally variable friction on the damage patterns. Tensile fractures form where tangential normal stresses...
