Several northeast-trending transverse faults cut the Purcell succession and parts of the Lower Paleozoic succession in the Hughes Range. Relationships along unconfonnities within and at the base of the Lower Paleozoic strata provide evidence of the natilre and timing of displacement on these faults. Field mapping of the faults and unconformities hounding three Lower Paleozoic formntions have be...

The Euphrates Plain (EP) experiences large interannual variability in vegetation cover, especially in areas of marginal rain-fed agriculture. Vegetation in this region is primarily limited by available soil moisture, as determined by winter precipitation, spring precipitation, and air temperature. Satellite analyses indicate that the springtime normalized difference vegetation index (NDVI) is n...

The morphotectonic analysis is a useful time-saving and cost-effective method to assess tectonic activity, especially in large regions. In this paper, the study was carried out Kerman city which southeast of Iran part Central structural zone. Despite occurrence numerous historical instrumental earthquakes around city, there gap earthquake records that has obscured its seismicity status. aim ide...

[1] We use interferometric synthetic aperture radar (InSAR) and broadband seismic waveform data to estimate source parameters of the 29 June 1992, Ms 5.4 Little Skull Mountain (LSM) earthquake. This event occurred within a geodetic network designed to measure the strain rate across the region around Yucca Mountain. The LSM earthquake complicates interpretation of the existing GPS and trilaterat...

investigation of velocity structure based on seismic wave propagation have been performed in recent years in different parts of iran that results obtained is effective in the analysis of seismic zones and locate earthquakes with reasonable accuracy. on a broad scale, the seismotectonics of southern iran are controlled by active convergence between the arabian and eurasian tectonic plates that a...

Slip rates of the right-lateral Owens Valley Fault lie at the center of an ongoing debate over the rheology and mechanics of lithospheric deformation in eastern California. Slip rates determined from paleoseismic records of surface rupture yield Late Pleistocene – Holocene rates of < 1mm/yr to ~2 mm/yr. The decadal velocity field across the valley, however, approaches ~6 mm/yr of right-lateral ...

In this paper, we apply an effective method to evaluate relative tectonic activity by applying several morph-tectonic indices that are useful in evaluating topography and tectonics. These include stream length-gradient, asymmetric factor, hypsometric index, curves, valley floor width height ratio, drainage basin shape, mountain front sinuosity. The study region of Wadi Al-Arish northern Sinai P...

[1] Data from BARGEN GPS stations around Yucca Mountain (YM) have been independently processed using GIPSY-OASIS and GAMIT/GLOBK. The RMS velocity differences between these solutions is 0.06 mm/yr (east component) and 0.10 mm/yr (north), indicating an ability to resolve tectonic signals >0.3 mm/yr with high confidence. Inversion of GPS station velocities for Eastern California Shear Zone (ECSZ)...
