Detailed analyses of teleseismic surface waves and body waves from the Guatemala e rthquake of February 4, 1976, show the following: (1) Left lateral displacement along a vertical fault with a strike varying from N66øE to N98øE is consistent with the teleseismic data. (2) The seismic moment was 2.6 X 102? dyn cm. The directivity ofthe surface wave radiation i dicates an asymmetric (1:2.3) bilat...

We use interferometric synthetic aperture radar (InSAR) observations to investigate the coseismic deformation and slip distribution of the 1997 Mw7.5 Manyi earthquake, a left-lateral strike-slip earthquake occurred on the west portion of the Kunlun fault in the northern Tibet, China. The fault trace is constrained by the combination of interferometric coherence image and azimuth offset image. T...

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 ...

Quantifying fault damage zones provides a window into stress distribution and rheology around faults. International Ocean Discovery Program (IODP) Expeditions 372/375 drilled an active thrust splay within the Hikurangi subduction margin. The fault, which is hosted in Pleistocene clastic sediments, surrounded by brittle fractures faults as well ductile deformation features. We find that fracture...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....

o bjectives: headgears are among the effective orthodontic appliances to achieve treatment goals. unilateral molar distal movement is sometimes needed during an orthodontic treat- ment, which can be achieved by an asymmetric headgear. different unilateral headgears have been introduced. the main goal of this study was to analyze the force system of uni- lateral expanded outer bow asymmetric hea...

It is often argued, both in popular and academic literature, that there are two Israels: one religious, benighted and anti-democratic and the other secular, Western and liberal. The fact that this account dominates public discourse in Israel tells us a great deal, but the account itself tells us little about Israeli society. Actually, the most telling fault line in Israeli society lies between ...

field observations of the incurred damages to the buildings and bridges due to earthquakes in near field show there are various failure modes which are in relation to the forces caused by vertical component. while vertical component of earthquake for ordinary buildings in most seismic regulations and standards is not considered. therefore, in the current study the effects of vertical and horizo...

We describe the morphology of a large and complex graben structure in the western Thauma-sia region (the " Thaumasia graben " [1] or TG). We consider possible fault geometries, determine extension , and discuss shortly possible models for its origin. Background: Situated at the western border of the Thaumasia plateau, the TG is one of the most prominent fault-bounded structures on Mars. It is ~...
