Generation of 6-C synthetic seismograms in stratified vertically transversely isotropic media using a generalized reflection and transmission coefficient method

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (3)

We develop a generalized reflection and transmission coefficient method (GRTM) for generating six-component (6-C) synthetic seismograms in horizontall......

A study of the lateral heterogeneity with the ellipticity of Rayleigh waves derived from microtremors

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (3)

We examine the potential of frequency-dependent Rayleigh wave ellipticity, derived from microtremors, for the investigation of heterogeneous subsurfac......

A unified description of surface waves and guided waves with relative amplitude dispersion maps

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 227 (3)

Compared with surface waves, guided waves are rarely applied in near-surface investigation. The main reason may lie in the complexity of their dispers......

Bulk modulus for fluid-saturated rocks at high frequency: modification of squirt flow model proposed by Mavko & Jizba

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (3)

The squirt flow model, proposed by Mavko & Jizba, has been widely used in explaining the frequency-related modulus and velocity dispersion between......

Phase-weighted slant stacking for surface wave dispersion measurement

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 226 (1)

Surface wave retrieval from ambient noise records using seismic interferometry techniques has been widely used for multiscale shear wave velocity (V-s......

A point dislocation in a layered, transversely isotropic and self-gravitating Earth. Part IV: exact asymptotic solutions of dislocation Love numbers for the special case of isotropy

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (1)

We derive exact asymptotic solutions for the static deformation due to a concentrated or point-like dislocation in a spherical, layered, elastic, isot......

Seismic evidence for a plume-modified oceanic lithosphere-asthenosphere system beneath Cape Verde

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (2)

We determine a new 3-D shear wave velocity (V-s) model down to 400 km depth beneath the Cape Verde hotspot that is far from plate boundaries. This V-s......

Controls on the present-day dynamic topography predicted from mantle flow models since 410 Ma

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (3)

Mantle convection induces dynamic topography, the lithosphere's surface deflections driven by the vertical stresses from sublithospheric mantle convec......

Modified frequency-Bessel transform method for dispersion imaging of Rayleigh waves from ambient seismic noise

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (2)

Ambient noise surface wave methods have gained much attention among geophysical and civil engineering communities because of their capability of deter......

Remagnetization of Jutal dykes in Gilgit area of the Kohistan Island Arc: Perspectives from the India-Asia collision

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 226 (1)

The Kohistan Island Arc (KIA) occupies the northwestern region of the Himalayan Mountains, sandwiched between Asia and India plates. Its formation, co......

Characterization of the near-surface shear wave attenuation in the Groningen gas field using borehole recording

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 226 (3)

The Groningen gas field located in the northern Netherlands is the largest gas field in Europe. Many induced earthquakes have occurred since the gas e......

Robust deep learning seismic inversion with a priori initial model constraint

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 225 (3)

Seismic inversion is one of the most commonly used methods in the oil and gas industry for reservoir characterization from observed seismic data. Deep......

Weighted multichannel singular spectrum analysis for post-processing GRACE monthly gravity field models by considering the formal errors

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 226 (3)

Gravity Recovery and Climate Experiment (GRACE) Spherical Harmonics (SH) solutions are usually provided together with the corresponding formal errors,......

Stability analysis-based reformulation of wave equations for poro-elastic media saturated with two fluids

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2021; 226 (1)

The stability of partial differential equations determines the properties of their solutions. This study focuses on the stability analysis of the equa......
