A paper by Shaozhuo Liu is online and soon to be published by the Journal of Geophysical Research with the title "Lower crustal heterogeniety beneath the northern Tibetan Plateau constrained by GPS measurements following the 2001 Mw7.8 Kokoxili earthquake. In the paper, Shaozhuo reports on post-seismic shear deformation across the Kokoxili earthquake rupture, observed by GPS, that appears to be primarily caused by viscoelastic relaxation in the lower crust and upper mantle. He also shows that the post-seismic deformation is strongly assymmetric accorss the fault, which he explains by lateral heterogenites in the lower crust, with one side having 2-4x higher viscosity than the other side. His co-authors of this study are Xiwei Xu, Yann Klinger, Jean-Mathieu Nocquet, Guihua Chen, Guihua Yu and Sigurjón Jónsson
