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...

Abstract The Moho – defined as the boundary that separates Earth’s crust from underlying upper mantle at depths of about 5 to 7 km beneath oceans and 30 40 below continents has been difficult pin down with observations. Different methods have yield a variety results, suggesting this simple definition may be misleading. Here, we present high-resolution deep penetrating seismic reflection data im...

The inversion of the teleseismic P-wave receiver functions was employed to determine structure crust under Anbar broadband seismic station. Some computer programs in seismology were used analyze nine earthquakes. Results show that crustal (Moho depth) beneath ANB1 station is 44 km. sedimentary cover thickness (basement at 12km. In general, obtained and thicknesses are consistent with results so...
