Dear Colleagues,

As you= think about the AGU meeting, please consider submitting to session G11, Pl= ate Motions and Plate Boundaries.

G11: Plate Motion and Plate Boundaries

We seek geodetic and geologic studies on plate mo= tion, microplate motion, and how they relate to elements in the deforming zones between the plates=97faults, slip, great earthquakes, and mountains and rifts generated by active deformation. In addition to well-studied regions and plates, we specifically solicit abstracts that address plate motions and plate boundary deformation in the more remote areas of the world, where data are limited. Among the questions we seek answer are: How accurately can we measure plate motions today using geodesy? What is the impact of uncertainties in geocenter motion, or in models of GIA and other non-tectonic processes on the estimation of plate motions? What are the proper uncertainties in plate motion estimates, especially where data are sparse? What fraction of plate motion is being taken up on major faults, and what fraction is being taken up by distributed permanent strain that is becoming part of the geologic record? Are deforming belts better described by microplates or by a homogeneous medium? Do estimates of plate motion from magnetic anomalies, transform azimuths, and earthquake slip vectors differ significantly from those from GPS, VLBI, SLR, and DORIS?
