Authors studied the enchanced signs and the dynamic monitoring method of the regional stress field, using the seismic activity and precursory data in China continent. The changes of the effects of lunar phase before strong shocks, spatial evolution features of regional seismicity and precursory field, spatial migration of moderate earthquake swarms, short-term dynamic mutation of large-scale precursory field, and the tracing of moderately strong seismicity in the China continent after occurrence of strong earthquakes are discussed. The enchance of dynamic monitoring for regional stress field will benefit the prediction of seismic trends and short-term and medium-term earthquake prediction and will provide significant background strong earthquakes.
