Finite element modeling of ground deformation and gravity field at Mt. Etna
numerical modeling gravity anomaly
2015/9/1
An elastic 3-D axi-symmetric model based on Finite Element Method (FEM) is proposed to compute ground deformation
and gravity changes caused by overpressure sources in volcanic areas. The numerical c...
The expanding Earth at present:evidence from temporal gravity field and space-geodetic data
station coordinates and vertical velocities temporal gravity variation principal inertia moments Earth expansion
2015/8/27
The Earth expansion problem has attracted great interest, and the present study demonstrates that the Earth has been expanding, at least over the recent several decades. Space-geodetic data recorded a...
A signal-strength model for gravity-field spectrum components in a local space
Earth's Gravitational Potential Local Area Spectrum Structure Spherical Cap Harmonic Analysi
