Unfaulting seismic images to correlate seismic reflectors across faults is helpful in seismic interpretation, and is useful for seismic horizon extraction. Methods for unfaulting typically assume that fault geometries need not change during unfaulting. However, for seismic images containing multiple faults and, especially, intersecting faults, this assumption often results in unnecessary distor...

The PYRAMID parallel unstructured adaptive mesh refinement (AMR) library has been coupled with the GeoFEST geophysical finite element simulation tool to support parallel active tectonics simulations. Specifically, we have demonstrated modeling of coseismic and postseismic surface displacement due to a simulated Earthquake for the Landers system of interacting faults in Southern California. The ...

Abstract Constraining the mechanisms of normal fault growth is essential for understanding extensional tectonics. Fault kinematics remain debated, mainly because very earliest phase deformation through recent syn-kinematic deposits rarely documented. To understand how underlying structures influence surface faulting, we examined in a 10 ka magmatically resurfaced region Krafla fissure swarm, Ic...

This paper addresses the problem of injection of faults in the communication system of disjoint memory parallel computers and presents fault injection results showing that 5% to 30% of the faults injected in the communication subsystem of a commercial parallel computer caused undetected errors that lead the application to generate erroneous results. All these cases correspond to situations in w...

This study reports on the cosmogenic 36Cl dating of two normal fault scarps in western Turkey, that Manast?r and Mug?rtepe faults, beyond existing historical records. These faults are elements Manisa Fault Zone (MFZ) seismically active Gediz Graben. Our modeling revealed underwent at least surface ruptures 3.5 ± 0.9 ka 2.0 0.5 ka, with vertical displacements 3.3 m 3.6 m, respectively. An event ...

Crustal scale fault zones extend below the brittle-ductile transition as ductile shear zones. Here we address question of which regime, brittle or ductile, initiates and controls overall system localization. Observations crustal but low displacement conjugate strike-slip faults show that they are typically nearly orthogonal, expected from plastic criteria. Sub-crustal faults, however, have acut...

High-quality 3D seismic reflection and well data are used to investigate the distribution, evolution history significance of tectonic faulting in a salt minibasin offshore Espírito Santo, SE Brazil. Displacement-length (D max -L) plots, displacement-depth (D-Z) plots structural maps compiled understand growth distinct fault families. Interpreted structures include crestal, corridor, listric key...
