We estimated Moho depths from data recorded by permanent and temporary broadband seismic stations deployed in northern Baja California, Mexico, using the receiver function technique. This region is composed of two subregions contrasting geological topographical characteristics: Peninsular Ranges California (PRBC), a batholith with high elevations (up to 2,600 m); Mexicali Valley (MV) region, se...

[1] We analyze teleseismic P waves from four Mw ≥ 6.5 earthquakes recorded by a petroleum industry survey in Long Beach, California. The survey used a 2-D array with up to 5200 seismometers, 120m mean spacing, and 7 – 10 km aperture. At frequencies near 1Hz, P wave travel times and amplitudes exhibit coherent lateral variations over scales as short as ~400m, including locally delayed travel tim...

in this study, we used teleseismic data which was recorded by 5 stations (dhr, ghg, kom, lin and vis) of the kermanshah seismic network from 2003 to 2007 with mb?5.5 and epicentral distances from 30° to 95°. the crustal structure beneath these stations was determined by the modeling of the p receiver functions. the main phases, which were observed in our final p receiver functions, are moho con...

The application of the pre-stack depth migration (PSDM) method using deep seismic reflection data is still a challenge. In this paper, dataset collected from Bohai Bay Basin used to test applicability method. After improving signal-to-noise ratio prestack gathers and building an accurate velocity model capturing lateral vertical variations, high-quality profile obtained. This shows detailed cru...

the khorasan region is one of the active seismic zones in iranian plateau, which is located between central iran and kopet-dagh zones. we study the crustal thickness (h) and vp/vs ratio (k) in mashhad, capital of razavi khorasan province by the receiver function method. this study uses teleseismic events recorded by an array of three broadband stations of khorasan seismic network, earthquake re...

Abstract The purpose of this study is to determine MOHV21, a Moho depth model based on an optimal combination five global seismic and gravimetric-isostatic models by weighted least squares approach at resolution 1° × 1°. For proper weighting among the data, starts with determining (mostly missing) standard errors correlations models. input range from 1.0 (in Brazil) 6.8 km Peru) 0.1 Huna Bay) 6...
