Updated velocity field for the Caribbean plate from COCONet GPS observations
Abstract
The currently accepted kinematic model of the Caribbean plate presented by DeMets et al., 2007, is based on velocities from 6 continuous and 14 campaign GPS sites. Our work attempts to refine the current plate model by evaluating data from the 60+ continuous GPS stations that comprise COCONet. COCONet (Continuously Operating Caribbean Observation Network) is an NSF-funded collaborative natural hazards research effort that has enhanced the geodetic infrastructure in the region surrounding the Caribbean plate. Data for this study was obtained from the open data archive at UNAVCO. GPS data have been processed with an absolute point positioning strategy using GIPSY-OASIS II, using the non-fiducial, final precise clock and orbit parameters provided by JPL. An updated velocity field for the Caribbean plate will be presented and co-seismic and post-seismic slip, recorded by network stations will be examined for earthquakes that have occurred within the COCONet footprint.
