SUMMARY:The motion and rheology of the Indian plate\, and their effects up
 on Tibetan tectonics - Alex Copley\, University of Cambridge
DTSTART:20101019T153000Z
DTEND:20101019T163000Z
UID:TALK26632@talks.cam.ac.uk
CONTACT:John Maclennan
DESCRIPTION:This seminar will describe three inter-related studies\, which
  together shed new light on the rheology and dynamics of the Indian plate 
 and the Tibetan Plateau. I will describe force-balance calculations which 
 can be used to estimate the forces acting upon the Indian plate\, and quan
 tify the effects of the India-Asia collision upon the motion of the plate.
  I will then describe a joint inversion of seismic and geodetic data for t
 he distribution of slip in the 2001 Mw 7.6 Bhuj earthquake. By comparing t
 he stress drop in the earthquake with the total force exerted upon the Ind
 ian plate by the Tibetan Plateau (estimated from the force-balance calcula
 tions) it is possible to investigate the rheology of the Indian lithospher
 e. Finally\, I will discuss the effects of this Indian lithosphere rheolog
 y upon the deformation of the Tibetan Plateau\, describing how spatial var
 iations in tectonic regime within the plateau are related to the material 
 properties of the Indian material which underthrusts its southern margin.
