GPS geodetic constraints on Caribbean - North America plate motion

We describe a model for Caribbean plate motion based on GPS velocities of four sites in the plate interior and two azimuths of the Swan Islands transform fault. The data are well fit by a single angular velocity, with average misfits approximately equal to the 1.5-3.0 mm yr -• velocity uncertainties. The new model predicts Caribbean-North America motion -65% faster than predicted by NUVEL-1A, a...

Imaging the Plate Interface in the Cascadia Seismogenic Zone: New Constraints from Offshore Receiver Functions

The Cascadia subduction zone, where the Juan de Fuca (JdF) plate subducts beneath North America, has paleoseismic evidence ofMw ∼9:0 megathrust earthquakes (Nelson et al., 1995; Goldfinger et al., 2003). However, there are virtually no instrumentally recorded thrust-zone earthquakes, hence the location and behavior of the seismogenic zone is known only indirectly. Temperature has been proposed ...

GPS snow sensing: results from the EarthScope Plate Boundary Observatory

Accurate measurements of snowpack are needed both by scientists to model climate and by water supply managers to predict/mitigate drought and flood conditions. Existing in situ snow sensors/networks lack the necessary spatial and temporal sensitivity. Satellite measurements currently assess snow cover rather than snow depth. Existing GPS networks are a potential source of new snow data for clim...
