A method for extracting the preseismic gravity anomalies over the Tibetan Plateau based on the maximum shear strain using GRACE data

Earth and Planetary Physics
The occurrence of earthquakes is closely related to the crustal geotectonic movement and the migration of mass, which consequently cause changes in gravity.

On the interpolation of high-frequency gravity field signals in mountainous areas

Contributions to Geophysics and Geodesy, 2013
The paper presents a comparison among different techniques in interpolating high-frequency gravity field signals in mountainous areas. A gap of 1◦ ×1◦ has been artificially created within the free-air gravity anomalies data set for Austria.

Sub‐Lithospheric Small‐Scale Convection Tomographically Imaged Beneath the Pacific Plate

Geophysical Research Letters, 2022
Small‐scale convection beneath the oceanic plates has been invoked to explain off‐axis nonplume volcanism, departure from simple seafloor depth‐age relationships, and intraplate gravity lineations.

Mare Orientale Gravity Anomaly [PDF]

Nature, 1970
SJOGREN has reported that there is an annular negative gravity anomaly surrounding a small positive anomaly over the central basin of Mare Orientale (paper given at the NATO Advanced Study Institute on the Moon and Planets, Newcastle, April 1970). I should like to point out that outside this negative ring, there is a positive ring and perhaps further ...

Multi-resolution analysis of gravity anomalies: A comparative study of modern and spherical approximation techniques

Nova Geodesia
Analysing gravity anomalies is a key method of understanding the Earth’s shape, structure, and subsurface composition. This is done by modeling the Geoid, an irregular surface, into a regular sphere or ellipsoid for easy computations.

Evaluation of Gravity Data Derived from Global Gravity Field Models Using Terrestrial Gravity Data in Enugu State, Nigeria

Journal of Geodetic Science, 2018
Spherical harmonic expansion is a commonly applied mathematical representation of the earth’s gravity field. This representation is implied by the potential coeffcients determined by using elements/parameters of the field observed on the surface of the ...

Short-cut to new anomalies in gravity duals to logarithmic conformal field theories

, 2011
Various massive gravity theories in three dimensions are conjecturally dual to logarithmic conformal field theories (LCFTs). We summarise the status of these conjectures. LCFTs are characterised by the values of the central charges and the so-called "new

Gravity anomalies without geomagnetic disturbances interfere with pigeon homing – a GPS tracking study

Journal of Experimental Biology, 2014
The gravity vector theory postulates that birds determine their position to set a home course by comparing the memorized gravity vector at the home loft with the local gravity vector at the release site, and that they should adjust their flight course to
