Several school buildings were surveyed in the disaster areas of the Marmara (17 August 1999, [Formula: see text]), Düzce (12 November 1999, [Formula: see text]), and Bingöl (1 May 2003, [Formula: see text]) earthquakes in Turkey. Among them, 21 rei

One of the goals of using the Global Positioning System (GPS) and other geodetic survey techniques in tectonics has been to detect boundaries such as faults or shear zones between rigid or mildly deforming crustal masses. The calculation of infinites

A mechanical model of forced-folding, comprised of an anisotropic cover overlying displaced, rigid basement blocks, is used to investigate the influence of various parameters on theoretical fold form: shape and dip of basement fault, strength of base

Previous workers have formulated velocity descriptions of the trishear kinematic model of fault propagation-folds, which are inherently non-unique. We present two complete mechanical models of fault-related folding and assess the validity of the assu

The fault trace of the 12 November 1999 earthquake in theDuzce-Bolu region in Anatolia crossed the alignment of a 2.4 kmviaduct in Kaynasli that had been carefully surveyed. The builders of theviaduct, the ASTALDI-BAYINDIR Co., resurveyed the viaduct

The subdivision of sedimentary rock layers by the formation of layer-parallel faults in a developing fold can be explained by a combination of intralayer weaknesses and internal layer-parallel shear stresses generated by bending. An analysis of stres

The postulate of premonitory shear zones that the orientations of many faults are controlled by previously formed shear zones is a combination of theoretical analysis and the concept that faulting is the result of a group of hereditary processes. The

The Landers, California, earthquake (Mw = 7.3) provides an exceptional opportunity to study surface rupture of an earthquake fault. Detailed maps of the lateral distribution of fracturing adjacent to main traces show that rupture patterns are much mo

The 1989 Loma Prieta, California, earthquake is characterized by the lack of major, throughgoing, coseismic, right-lateral faulting along strands of the San Andreas fault zone in the epicentral area. Instead, throughout the Summit Ridge area there ar

High-amplitude folding of viscous multilayers during shortening can be analyzed with a theoretical solution motivated by first-order theoretical analysis of folding by Raymond Fletcher and Ronald Smith. The solution method can better match boundary c
