Abstract: According to grey systematic theory, a grey zonation of seismic risk in southern Liaoning Province has been proposed in this paper, based on seven environmental factors such as seismicity,active fault,Bonger gravity anomaly etc.As a result,southern Liaoning Province has been regionalized into extremely dangerons, dangerous, less dangerous aud safe regions, respectively.

Key words: Liaoning Province, Seismic risk, Grey zonation
