TL;DR: For many common GPS/GLONASS native receiver formats, a single freeware program called TEQC now allows the user to translate from the binary receiver format to the standard Receiver Independent Exchange (RINEX) format, to edit existing RINEX files, and to quality-check the data before postprocessing.

TL;DR: In this paper, the authors describe how GPS measurements of horizontal crustal motion can be used to augment vertical motion measurements, to improve and extend GPS studies of surface loading, and show that the ratio of the vertical displacement to the horizontal displacement, combined with the direction of the horizontal motion, can help determine whether nearby loading is concentrated in a small region (for example, in a single lake or glacier).

TL;DR: The results of geodetic monitoring since 2002 at Sierra Negra volcano in the Galapagos Islands show that the filling and pressurization of an ∼2-km-deep sill eventually led to an eruption that began on 22 October 2005.

TL;DR: In this article, the authors interpret the swarm as resulting from a dike intrusion and model the deformation field using a constant pressure dike source, and find the model that best fits the data.

TL;DR: In this paper, GPS data revealed periods of uplift and subsidence of the Yellowstone caldera at rates up to 15 mm/yr, which exceeded historic seismic moment release and late Quaternary fault slip-derived moment release by an order of magnitude.
