Abstract：This article introduces the method of factor analysis. It conducts comprehensive analyses on 16 seismic activity parameters of the small and medium-sized earthquake sequences in the Pingyuan earthquake area. The results show that the current comprehensive factor W was in the highest value range of this quiet episode. Further research of the single factors reveals that the underground medium in the Pingyuan earthquake area might have undergone some changes. In the future, seismic activity in north China may increase.
