| Abstract: | We used the 5 002 P wave polarity data in Heilongjiang Province, two-dimensional stress structure is invered and 0.5°×0.5° focal mechanism solutions are obtained by the composite focal mechanism method. The preliminary study shows that： the tectonic stress field charac- teristics is uniformity since twenty-first century. It has obvious inheritance. The predomi- nant direction of the main pressure stress and tensile stress is evident. It can be contributed to plate movement in the region. |
