Timing and Rates of Quaternary Normal Faulting in Central Tibet
In Summer 1998, a 400 km long seismic refraction profile (INDEPTH III) was shot in Central Tibet. Apart from recording the signals of 11 shots along the line, the stations also recorded a number of local earthquakes more or less in the extension of the line. Record sections and travel time data from both shots and earthquakes were compiled and interpreted jointly. The following peculiarities ar...
متن کاملPost-Triassic normal faulting and extensional structures in Central Alborz, Northern Iran
This paper presents structural evidence of extensional activity in Central Alborz during Mesozoic. The structural evidence of homogenous early stage stretching such as layer-parallel to oblique boudinage of Permian and Triassic rocks in various portions of the study area accompanied by extensional-fibrous fractures were followed with more advanced extensional features. These extensional structu...
متن کاملTectonic Implications of Subcrustal, Normal Faulting Earthquakes in the Western Shikoku Region, Japan
Tectonic implications of subcrustal, normal faulting earthquakes in the western Shikoku region have been investigated in sorme detail, mainly based on the faulting mechanism of the Bungo channel earthquake of August 6, 1968 (M=6.6, h=45km) and its aftershocks. A synthetic study of the focal mechanism solution, spatial distribution of aftershocks, seismic waves observed in the near and far field...
متن کاملNormal faulting sequence in the Pumqu-Xainza Rift constrained by InSAR and teleseismic body-wave seismology
Normal faulting earthquakes play an important role in the deformation of continents, and pose significant seismic hazard, yet important questions remain about their mechanics. We use InSAR and bodywave seismology to compute dislocation models and centroid moment solutions for four normal-faulting earthquakes (Mw 5.7–6.2) that occurred in the Pumqu-Xainza Rift (PXR), southern Tibet, a region whe...
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 ...
