Shanxi subsidence basin is an important area in North China, where strong earthquakes(M=6.0)always visit. This paper deals with the location of epicenters of the earthquakes, the isoseismal lines, the temporal sequences and the tectonic strike of all the strong earthquakes(M=6.0)in this area.
The following preliminary results can be done in this paper:
In the same subsidence basin, there are earthqakes of M=6.0 which occur repeatedly in the same spot with approximate magnitude, short interval, oblique or normal strike and the different kinds of seismogenic structure.
