TL;DR: In this article, the ionospheric electron content time series for several days preceding and following the January 17, 1994, M(sub w) = 6.7 Northridge earthquake was used to compute ionoispheric electron density.

TL;DR: In this article, the authors describe a model for the Caribbean plate motion based on GPS velocities of four sites in the plate interior and two azimuths of the Swan Islands transform fault.

TL;DR: In this article, the authors present a velocity field for Western Europe and the Western Mediterranean derived from a rigorous combination of a selection of sites from the ITRF2000 solution, a subset of site from the European Permanent GPS Network solution, and a solution of the French national geodetic permanent GPS network (RGP) in the western Alps (REGAL).

TL;DR: In this paper, the experimental accuracy of GPS measurements for the continuous monitoring of landslides with GPS is evaluated. But the results are limited by the environmental characteristics of the geophysical object (mountains, vegetation), which can constitute masks limiting the visibility of the sky and create multipath effects.

TL;DR: In this article, the authors compute poles of rotation for the Australia, Eurasia, and Pacific plates based on the analysis of the global GPS data and find that regional tectonics is dominated by the interaction of four discrete, rotating blocks spanning significant areas of the Sunda Shelf, the South Banda arc, the Bird's Head region of New Guinea, and East Sulawesi.
