The 1999 M w 7 . 1 Hector Mine , California , Earthquake Sequence : Complex Conjugate Strike - Slip Faulting
The 1999 Mw 7.1 Hector Mine mainshock showed right-lateral strikeslip faulting, with an initial strike of N6 W and vertical dip. The mainshock was preceded within 20 hours by 18 recorded foreshocks of 1.5 M 3.8 within a few kilometers distance of the mainshock hypocenter. The aftershocks delineate how the Hector Mine earthquake ruptured with strike N6 W to the south for a distance of 15 km, and...
متن کاملRefinement to the Existing Analytical Methods of Analysis of Buried Pipelines due to Strike-Slip Faulting
Analytical methods presented to analyze the buried steel pipelines at strike-slip fault crossing use the Euler-Bernoulli beam theory. The cross-section of a buried pipe that is completely surrounded by soil cannot rotate freely and would not be remained perpendicular to the bending line after deformation. So it would be better to take into consideration a rotation between the cross-section and ...
متن کاملThe mechanics of first order splay faulting: The strike-slip case
First order splay faults, as defined here, are secondary faults that form at acute angles symmetrically on either side of a primary fault of the same sense of shear. We show that these faults form when the primary fault becomes critically misaligned with the principal stresses such that splay fault formation, on the optimum plane for faulting, is favored. First order splay faults, in distinctio...
متن کاملConjugate strike-slip faulting along the Bangong-Nujiang suture zone accommodates coeval east-west extension and north-south shortening in the interior of the Tibetan Plateau
[1] Geologic investigations of how the Tibetan plateau is currently deforming have focused primarily on its boundary faults. Consequently, how the interior of the plateau deforms remains poorly understood. To fill this gap in knowledge, we conducted field mapping, analysis of remote sensing and digital topographic data, and reinterpretation of existing geologic maps in central Tibet. This study...
متن کاملBookshelf faulting in Nicaragua
Oblique subduction at a high rate of convergence along much of the Middle America Trench results in northwest-directed trench-parallel block motion. Accommodation of this motion along northwest-striking dextral strike-slip faults has been postulated; however, in Nicaragua such faults are not well developed. We suggest instead that this motion is accommodated by bookshelf faulting that includes ...
