TLDR
In this paper, a suite of closed analytical expressions for the surface displacements, strains, and tilts due to inclined shear and tensile faults in a half-space for both point and finite rectangular sources are presented.Abstract:
A complete suite of closed analytical expressions is presented for the surface displacements, strains, and tilts due to inclined shear and tensile faults in a half-space for both point and finite rectangular sources. These expressions are particularly compact and free from field singular points which are inherent in the previously stated expressions of certain cases. The expressions derived here represent powerful tools not only for the analysis of static field changes associated with earthquake occurrence but also for the modeling of deformation fields arising from fluid-driven crack sources.read more

Radar interferometry and its application to changes in the Earth's surface
Didier Massonnet,Kurt L. Feigl +1 more
TL;DR: In this paper, a review of the use of radar interferometry to measure changes in the Earth's surface has exploded in the early 1990s, and a practical summary explains the techniques for calculating and manipulating interferograms from various radar instruments, including the four satellites currently in orbit: ERS-1, ERS2, JERS-1 and RADARSAT.

The displacement field of the Landers earthquake mapped by radar interferometry
Didier Massonnet,Marc Rossi,César Carmona,Frédéric Adragna,Gilles Peltzer,Kurt L. Feigl,Thierry Rabaute +6 more
TL;DR: In this article, the authors used Synthetic Aperture Radar (SAR) interferometry to capture the movements produced by the 1992 earthquake in Landers, California, by combining topographic information with SAR images obtained by the ERS-1 satellite before and after the earthquake.

TL;DR: In this article, an elastic block model was developed to constrain present-day plate motions (relative Euler vectors), regional deformation within the interplate zone, and slip rates for major faults.

A silent slip event on the deeper Cascadia subduction interface.
TL;DR: Continuous Global Positioning System sites in southwestern British Columbia, Canada, and northwestern Washington state, USA, have been moving landward as a result of the locked state of the Cascadia subduction fault offshore, and a cluster of seven sites briefly reversed their direction of motion in the summer of 1999.

The displacement fields of inclined faults
Lalu Mansinha,D. E. Smylie +1 more
TL;DR: In this article, closed analytical expressions for the displacement fields of inclined, finite strike-slip and dip-slink faults are given, and they may be readily used in the numerical computation of displacements, and by differentiation, strain and stress fields may be derived.

The deformation of the ground around surface faults
TL;DR: In this article, a rectangular dislocation surface (i.e., a surface across which there is a discontinuity in the displacement vector) is used as a model of a vertical transcurrent fault and the results of Steketee (1958a) are employed to derive, in analytical form, the displacement field throughout a semi-infinite elastic medium due to such a dislocation.

Displacements, strains, and tilts at teleseismic distances
TL;DR: In this paper, the dislocation theory representation of faulting is used to compute the residual displacement, strain, and tilt fields at intermediate and large distances from major earthquakes, and it is shown that the distant fields are large enough to be detected by modern instruments.

The stress changes that accompany strike-slip faulting
TL;DR: Chinnery as discussed by the authors investigated the deformation of the ground around a strike-slip fault and the change in stress distribution that is brought about by such a fault, both for the general rectangular fault and for the limiting case of a long shallow fault.
