Plate boundaries for NNR-MORVEL56 model
Tar file of NNR-MORVEL56 plate boundaries
Zip file of NNR-MORVEL56 plate boundaries
The links above are to tar and zip archives that contain simple ASCII files
that specify the enclosed boundaries of all 56 plates that were used to derive
the NNR-MORVEL56 no-net-rotation angular velocities. Each tar and zip archive
contains one plate geometry file for each of the 56 plates, plus a single file
that includes the geometries of all 56 plates. Each file name is coded to an
individual plate. Each file contains a 2-column sequence of latitude/longitude plate
boundary coordinates that fully enclose the plate.
Forty-nine of the 56 plate geometries in this file are identical to those in
Bird (2003). The other seven plate geometry files enclose plates that are unique
to MORVEL or whose geometries were modified from Bird (2003). Our plate boundaries differ
from Bird's only for the Somalia-Lwandle, Australia-Capricorn, Australia-Macquarie,
and South America-Sur plate boundaries. Interested users should refer to Bird (2003)
for a detailed explanation of how he defined the plate boundaries from seafloor spreading
magnetic anomalies, topography, earthquake epicenters, and volcano locations. Please cite
Bird (2003) and Argus et al. (2011) as the source of these plate boundaries.
