SUMMARY:Using dynamic models to understand continental deformation - Alex

DESCRIPTION:The Earth's oceans are underlain by large\, rigid\, tectonic p
 lates\, which only deform along narrow zones at their boundaries. In contr
 ast\, many areas of the continents undergo pervasive deformation over regi
 ons thousands of kilometres wide. The characteristics of earthquakes\, and
  estimates of surface motion made using highly-accurate GPS receivers\, te
 ll us about the active deformation in these wide deformation belts. Howeve
 r\, a quantitative physical understanding of the deformation has remained 
 elusive. I will describe a series of dynamic models that have shed new lig
 ht on the factors that control the characteristics of continental deformat
 ion\, and specifically focus on what controls the sizes\, shapes\, and evo
 lution through time of large mountain ranges such as the Tibetan Plateau.
