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.
