SPACE GEODESY AND GLOBAL PLATE MOTIONS
Space geodetic techniques provide measurements that can be used to infer
crustal deformation over global scales and can be compared with predictions
from conventional global plate motion models, which average motion over
millions of years.
In the past 5 years the scope and accuracy of space geodetic techniques has
expanded greatly. In some regions geodetic measurements are probably
more accurate than conventional global plate motion models.
In this session we focus on space geodetic techniques and their contribution to
understanding plate motion and intraplate deformation.
E.g., are there any decisive differences between angular velocities
inferred from geodetic data and those of NUVEL-1A, which is
mainly based on data averaged over 3 million years?
What part of these differences are caused by inaccuracies in global plate
motion models and what part is due to non-steady plate motions?
What bounds can be placed on intraplate deformation?
How is relative plate motion accommodated within diffuse plate
boundaries? Do velocities for island and non-island sites agree equally well
with plate predictions?
We welcome studies using GPS, VLBI, SLR, DORIS, doppler, "conventional"
plate motion approaches, or any combination of these techniques.
