As parallel processing hardware becomes more common and affordable, multiprocessors are being increasingly used to accelerate VLSI CAD algorithms. The problem of partitioning faults in a parallel test generation/ fault simulation (TG/FS) environment has received very little attention in the past. In a parallel TG/FS environment, the fault partitioning method used can have a significant impact o...

We propose a new method for defining segmentation of plate boundaries and faults, based on the directions of the stress tensor. Estimates for these directions are obtained by minimizing the average misfit between the theoretical and observed slip directions on fault planes of earthquake focal mechanisms. The misfit, f, for an individual earthquake is the parameter we use for defining the segmen...

Tectonic motion across the Los Angeles region is distributed across an intricate network of strike-slip and thrust faults that will be released in destructive earthquakes similar to or larger than the 1933 M6.4 Long Beach and 1994 M6.7 Northridge events. Here we show that Los Angeles regional thrust, strike-slip, and oblique faults are connected and move concurrently with measurable surface def...

Qaleh-Zari is a Fe-oxide Cu-Ag-Au vein type deposit located 180 km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline with transition to shoshonitic andesite and andesitic basalts, but in the central part shale and sandstone of Jurassic age. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5 ± 2 Ma. Four trends of faults...

In Southern California, plate boundary motion between the North American and Pacific plates is distributed across several sub-parallel fault systems. The offshore faults of California Continental Borderland (CCB) are thought to accommodate ∼10–15% total motion, but exact distribution slip mechanics partitioning remain uncertain. Newport-Inglewood-Rose Canyon easternmost within CCB whose souther...
