AGU Session G12: Plate Motion and How It Is Taken Up in Deforming Zones

Forwarded AGU session announcement from Jeffrey Freymueller, Alaska:

Last chance! Please consider submitting an abstract to session G12:

G12: Plate Motion and How It Is Taken Up in Deforming Zones

We seek geodetic and geologic studies on plate motion, microplate motion, and how they relate to structural elements in the deforming zones between the plates-faults, great earthquakes and seismicity, and mountains and rifts reflecting active deformation. We seek also studies investigating the following questions: How uncertain are estimates of plate motion? How well do geodetic and geologic estimates of plate motion agree, and are differences due to changing plate motion? To what degree can elastic strain that is going to be released in an earthquake be distinguished from permanent deformation that is becoming part of the geologic record? Where are deforming belts better described by microplates or where are they better described by a continuum? Where are the limits of the plate interiors? How are the plate interiors deforming in viscous response to unloading of the late Pleistocene ice sheets, and how are the plates deforming in elastic response to current ice sheet changes? How do SLR, VLBI, GPS, and DORIS estimates of plate motion depend on assumptions about Earth's reference frame?

Sincerely,
Donald F. Argus
