Far-field crustal movements before and after the 2011 Ms9.0 Japan earthquake from GPS observations

The paper gives an analysis of the displacement time series before and after the March 11, 2011 Ms9. 0 east Japan earthquake and co-seismic displacements observed at continuous GPS stations in and around China. The results showed a broad-scaled related elastic-rebound process and some premonitory horizontal crustal movements to this earthquake over this vast area.
