Assessing the stability of AOD1B atmosphere-ocean non-tidal background modelling for climate applications of satellite gravity data: long-term trends and 3-hourly tendencies

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 234 (2)

The GRACE Atmosphere and Ocean Level-1B (AOD1B) product is routinely applied in the processing of satellite gravimetry data to mitigate the impact of ......

Coseismic deformation of the 1976 Ms 7.3 Chaldiran earthquake in eastern Turkey measured by satellite imagery, in comparison with field measurements

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 234 (2)

Large continental earthquakes are infrequent, but they are important for understanding active tectonics. Many pre-1990, magnitude greater than 7 earth......

The coherence function and lithospheric elastic thickness of the Zagros fold and thrust belt

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 234 (2)

This study derives the spatial variation of the elastic thickness (Te) and its implications for understanding the structure, geodynamic and seismicity......

Estimation of fluid salinity using coseismic electric signal generated by an earthquake

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 233 (1)

The seismoelectric effect is a coupling phenomenon between the seismic wavefield and electromagnetic field caused by the electric double layer in a fl......

A superconducting gravimeter on the island of Heligoland for the high-accuracy determination of regional ocean tide loading signals of the North Sea

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 234 (3)

The superconducting gravimeter GWR iGrav 047 has been installed on the small offshore island of Heligoland in the North Sea approximately at sea level......

Coseismic drop of seismic velocity caused by the 2023 Turkey-Syria earthquakes

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 234 (3)

The M-w 7.8 earthquake in Turkey on 6 February 2023 was extraordinary for various reasons. It originated in depth of only 10 km, ruptured along a faul......

Model order reduction for seismic waveform modelling: inspiration from normal modes

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 234 (3)

The computational cost of full waveform simulation in seismological contexts is known to be expensive and generally requires large clusters of compute......

Quantification of spatial and seasonal trends in the atmosphere and construction of statistical models for infrasonic propagation

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 235 (2)

Infrasonic waves are influenced by variations in the density, pressure and temperature as well as the ambient winds. Modelling infrasonic propagation ......

Post-seismic gravity change modelling based on non-linear power-law upper mantle rheology

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 235 (3)

Post-seismic gravity change modelling is commonly based on earth model with Newtonian linear rheology. Here, we present a novel way of modelling post-......

High velocity lower crust with anomalous rheological parameters under the Red Sea Passive Margin, SW Saudi Arabia - insight into the evolution of the Hijaz-Asir Escarpment Zone

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 236 (1)

The Red Sea Passive Margin (RSPM) in SW Saudi Arabia is characterized by two morphological provinces; the Red Sea Coastal Plains (RSCP) and the Hijaz-......

Large-scale earthquake sequence simulations on 3-D non-planar faults using the boundary element method accelerated by lattice H-matrices

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 232 (3)

Large-scale earthquake sequence simulations using the boundary element method (BEM) incur extreme computational costs through multiplying a dense matr......

Effects of Earth's gravitation and compressibility on co- and post-seismic deformations

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 232 (3)

In this paper, we systematically analyse the effect of Earth's gravitation and compressibility on co- and post-seismic deformations. Based on the anal......

Heterogeneous seismic anisotropy beneath Madeira and Canary archipelagos revealed by local and teleseismic shear wave splitting

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 233 (1)

Mid-plate upward mantle flow is a key component of global mantle convection, but its patterns are poorly constrained. Seismic anisotropy is the most d......

Seismic wave dispersion and attenuation resulting from multiscale wave-induced fluid flow in partially saturated porous media

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 236 (2)

Sedimentary rocks are typical heterogeneous porous media induced by fluid patches and pore fabric. It is well acknowledged that the wave-induced fluid......

Qualitative and quantitative comparison of the genetic and hybrid genetic algorithm to estimate acoustic impedance from post-stack seismic data of Blackfoot field, Canada

期刊: GEOPHYSICAL JOURNAL INTERNATIONAL, 2023; 233 (2)

In this study, seismic inversion is carried out using a genetic algorithm (GA) as well as a hybrid genetic algorithm (HGA) approach to optimize the ob......
