The ground motion and damage caused by the 2015 Gorkha, Nepal earthquake can be characterized by their widespread distributions to the east. Evidence from strong ground motions, regional acceleration duration, and teleseismic waveforms indicate that rupture directivity contributed significantly to these distributions. This phenomenon has been thought to occur only if a strike-slip or dip-slip r...

the nayband strike-slip fault forms the western margin of the micro-continental lut block in eastern iran. neogene and quaternary mafic volcanic rocks collected near tabas, along the northern part of the fault (nnf; 15 ma), and further to the south, along the middle part of the fault (mnf; 2 ma), are within-plate sodic-series alkali olivine basalts with high tio2 and up to >16% normative nephel...

[1] We combine a viscoelastic model for the interseismic process and an elastodynamic model for the coseismic process to explore the dynamics (over multiple earthquake cycles) of two parallel strike-slip faults embedded in a two-dimensional full space. The step over fault geometry results in a buildup of heterogeneous fault stress near the step over. This heterogeneous stress accumulates at the...

The study area is located in the vicinity of Johanson Lake, some 350 kilometres north-northwest of Prince George, bounded t1! the northeast by the north-northwesttrending Lay fault i lnd to the southwest by Willow Creek. The north-northwes1:-trending Finlay-lngenika fault, one of the very prominent clextral strike-slip fault systems ofnorthcentral British Columbia (Gabrielse, IYXS), passes th...

the sangbast-shandiz fault zone, with a length of about 57 km, a width of moderately 2 km, and a nw-se direction, is located about 15 km in the west of mashhad city. that is one of the major faults in the binalud mountains. geomorphic evidences illustrate that the sangbast-shandiz fault zone has dextral strike- slip offsets with thrust activity. in this article, we investigated geomorphic featu...

T he Bight Basin is a major frontier basin of Jurassic–Cretaceous age, which is currently undergoing renewed exploration interest. Although only limited data is available for understanding the petroleum systems in the basin, several observations indicate that poor fault seal integrity may represent a key exploration risk. The presence of a paleo-oil column in the Jerboa-1 well, interpreted gas ...

S U M M A R Y We perform a systematic analysis of crustal anisotropy along and around the Karadere–Düzce branch of the North Anatolian fault (NAF), which ruptured during the 1999 Mw 7.4 İzmit and Mw 7.1 Düzce earthquakes. A method consisting of an iterative grid search for the best shear wave splitting parameters in sliding time windows is applied to ∼22 000 measurements recorded in the 6-month...

Alborz Mountains is a region of active deformation within Arabia-Eurasia collision zone. The study fault system in western Alborz comprises abundant evidence of active faulting accompanied by occurrence of historical earthquakes. Active tectonics of Manjil-Rudbar fault zone whose movement caused destructive 1990 Manjil-Rudbar earthquake was concentrated in this article through geomorphic and st...

In this study, Interferometric Synthetic Aperture Radar (InSAR) was used to determine the seismogenic fault and slip distribution of the 3 July 2015 Pishan earthquake in the Tarim Basin, western China. We obtained a coseismic deformation map from the ascending and descending Sentinel-1A satellite Terrain Observation with Progressive Scans (TOPS) mode and the ascending Advanced Land Observation ...
