Exact computation of the gravitational field and gravitational gradient tensor for a general
mass body is a core routine to model the density structure of the Earth. In this study, we …

Although observation of gravity perturbations induced by earthquakes is possible, simulation
of seismic wave propagation in a self-gravitating, rotating Earth model with 3-D …

Knowledge of deformation at plate boundaries has been improved greatly by the
development of observational techniques in space geodesy. However, most theoretical and …

ABSTRACT A new high-order compact (HOC) cascadic multigrid (MG) strategy is developed
for modeling large-scale complex gravity problems on nonuniform rectilinear grids. First, the …

Accurate and efficient simulations of coseismic and post-earthquake deformation are
important for proper inferences of earthquake source parameters and subsurface structure …

Gravity anomalies generated by density non-uniformity are governed by the 3D Poisson
equation. Most existing forward methods for such anomalies rely on integral techniques and …

The streaming potential in porous media is one of the main constituents of the self-potential.
It has attracted special attention in environmental and engineering geophysics. Forward …

Although earthquake-induced gravity perturbations are frequently observed, numerical
modelling of this phenomenon has remained a challenge. Due to the lack of reliable and …

In this study, we developed a novel hybrid approach for 3D controlled-source
electromagnetic (CSEM) forward modeling. The hybrid approach combines vector spectral …

We introduce a new efficient spectral element approach to solve the two-dimensional
magnetotelluric forward problem based on Gauss–Lobatto–Legendre polynomials. It …
