The figure below, from Penn State, shows co-seismic slip - movement on the fault itself. The red dots are actually locations of the main earthquake and aftershocks.
From the figure caption: A preliminary comparison of an estimate of coseismic slip (created in collaboration with Thorne Lay at UC Santa Cruz and Hiroo Kanamori at CalTech) with the aftershocks and bathymetry. The rainbow-filled circles show the slip pattern for the Mw 9.0 earthquake. The deeper red circles are the aftershock locations.
