TLDR
In this article, the static deformation of an elastic half-space by surface pressure is reviewed and a brief mention is made of methods for solving the problem when the medium is plane-strategized, but the major emphasis is on the solution for spherical, radially stratified, gravitating earth models.Abstract:
The static deformation of an elastic half-space by surface pressure is reviewed. A brief mention is made of methods for solving the problem when the medium is plane stratified, but the major emphasis is on the solution for spherical, radially stratified, gravitating earth models. Love-number calculations are outlined, and from the Love numbers, Green's functions are formed for the surface mass-load boundary-value problem. Tables of mass-load Green's functions, computed for realistic earth models, are given, so that the displacements, tilts, accelerations, and strains at the earth's surface caused by any static load can be found by evaluating a convolution integral over the loaded region.read more

Validation of ocean tide models around Antarctica using onshore GPS and gravity data
TL;DR: In this article, GPS data from 15 sites have been used to derive three-dimensional displacement estimates at eight diurnal and semidiurnal tidal frequencies, which were then compared with OTL displacement estimates derived from global and regional ocean tide models.

Nontidal ocean loading: amplitudes and potential effects in GPS height time series
TL;DR: In this paper, the amplitude of the predicted effect of OBP on the height coordinate time series from a global distribution of GPS stations was reassessed using more recent OBP estimates from the Estimating the Circulation and Climate of the Ocean (ECCO) project.

Global surface-water-induced seasonal variations in the earth's rotation and gravitational field
TL;DR: In this paper, the effects of seasonal changes in continental surface-water storage on the low-degree gravitational field coefficients (J), the annual wobble excitation (Psi), and the seasonal length-of-day (LOD) variations are investigated by means of numerical simulations based on compiled meteorological data and satellite snow-load estimates.

Seasonal water storage, stress modulation, and California seismicity.
TL;DR: In this article, the authors used 9 years of global positioning system (GPS) vertical deformation time series to constrain models of monthly hydrospheric loading and the resulting stress changes on fault planes of small earthquakes.

Earthquake Swarms and the Semidiurnal Solid Earth Tide
TL;DR: In this paper, the phase and stress orientation of the calculated solid earth tide is correlated with the number of swarm earthquakes, and the size of the aftershocks of the Rat Islands earthquake.

The finite element method in engineering science
TL;DR: In this paper, the authors describe how people search numerous times for their favorite books like this the finite element method in engineering science, but end up in malicious downloads, and instead they cope with some infectious bugs inside their computer.

Uniqueness in the Inversion of Inaccurate Gross Earth Data
George E. Backus,Freeman Gilbert +1 more
TL;DR: In this article, it was shown that a given set G of measured gross Earth data permits such a construction of localized averages, and if so, how to find the shortest length scale over which G gives a local average structure at a particular depth if the variance of the error in computing that local average from G is to be less than a specified amount.
