Thickness of Crust in the West of Iran Obtained from Modeling of Ps Converted Waves
Receiver functions are usually used to detect Ps converted waves and are especially useful to picture seismic discontinuities in the crust and upper mantle. In this study, the P receiver function technique beneath the west Iran is used to map out the lateral variation of the Moho boundary. The teleseismic data (Mb ≥5.5, epicentral distance between 30˚-95˚) recorded from 2004 to 2016 at 17 perma...
متن کاملEarthquake Precursors Assessment in Vrancea Area, Romania by Satellite and Geophysical In-situ Data
Earthquake prediction has two potentially compatible but distinctly different objectives: (a) phenomena that provide information about the future earthquake hazard useful to those who live in earthquake-prone regions and (b) phenomena causally related to the physical processes governing failure on a fault that will improve our understanding of those processes. For seismic hazard analysis in Vra...
متن کاملStacked P-to-S and S-to-P receiver functions determination of crustal thickness, Vp, and Vs: The H-V stacking method
H-κ stacking is a routinemethod for determining crustal thickness (H) and Vp/Vs (κ) using P-to-S (Ps) receiver functions. In this paper we show that S-to-P (Sp) receiver functions may also be used to determine crustal parameters. Sp provides independent information, complementary to Ps. We develop a method called H-V (crustal thickness-velocity) stacking where Ps and Sp receiver functions are s...
متن کاملMantle discontinuity structure beneath the southern east pacific rise from P-to-S converted phases
Receiver functions derived from teleseismic body waves recorded by ocean-bottom seismometers on the southern East Pacific Rise reveal shear waves converted from compressional waves at the mantle discontinuities near 410- and 660-kilometer depth. The thickness of the mantle transition zone between the two discontinuities is normal relative to the global average and indicates that upwelling benea...
متن کاملNeutron Star Crustal Interface Waves
The eigenfrequencies of nonradial oscillations are a powerful probe of a star’s interior structure. This is especially true when there exist discontinuities such as at the neutron star (NS) ocean/crust boundary, as first noted by McDermott, Van Horn & Hansen. The interface mode associated with this boundary has subsequently been neglected in studies of stellar nonradial oscillations. We revisit...
