seismic study of upper mantle beneath the nw iran using p receiver function
rf method is now a well-known tool for studying crustal and upper mantle structure when such a complete data set is available. we compute p receiver functions to investigate the upper mantle discontinuity beneath the northwest of iran. we selected data from teleseismic events (mb ? 5.5, 30 ?>? > 95?) recorded from 1995 to 2008 at 8 three component short period stations from tabriz telemetry sei...
متن کاملTomographic image of crust and upper mantle off the Boso Peninsula using data from an ocean-bottom seismograph array
We determined the three-dimensional structure of the crust and upper mantle off the Boso Peninsula, Japan, by analyzing seismograms recorded by ocean-bottom seismometers and land stations between 2011 and 2013. We employed seismic tomography to determine the Pand S-wave velocity structures and earthquake locations simultaneously. The tomographic image shows that the mantle parts of the Pacific ...
متن کاملSeismic structure in the mantle beneath Australia
The exposed geology of the Australian continent is composed of an assemblage of crustal blocks that can be broadly grouped into the Precambrian western and central cratons and the Phanerozoic eastern province (Figure 1). Structural differences between the Precambrian shield and eastern Australia are inferred from surface-wave dispersion (Muirhead & Drummond 1991; Denham 1991) and teleseismic tr...
متن کاملInvestigation of upper mantle discontinuity structure beneath the central Pacific using SS precursors
Figures S1-S9 show topologies for stacking parameters not explored in Figure 14 of the manuscript, and may be of interest to the reader. These additional plots demonstrate the agreement between topologies across the different stacking parameters, such as the corner frequency of the low-pass filter, correction models, and SNR value. The stacking geometry in all the supplemental plots is 80 10-de...
متن کاملUpper mantle anisotropy beneath the Geoscope stations
Seismic anisotropy has been widely studied this last decade, particularly by measuring splitting of vertically propagating core shear waves. The main interest in this technique is to characterize upper mantle flow beneath seismic stations. On the other hand, the major restriction in this method is that a single station gives a single anisotropy measurement. Alternative methods have been develop...
