Rapid mantle flow with power-law creep explains deformation after the 2011 Tohoku mega-quake

Large subduction zone earthquakes like the M 9.0 Tohoku earthquake of 2011 are followed by transient surface deformation. Here, the authors show this to be caused by rapid flow taking place in the asthenosphere due to temporarily decreased viscosity because of coseismic stress.
