SOME CHARACTERISTICS OF SEISMIC ACTIVITIES BEFORE AND AFTER STRONG EARTHQUAKES IN LIAO-KAO BELT |
| |
| Abstract: | In this paper, the seismic activity patterns before and after three historical strong earthquakes in Liao-kao belt, as well as the seismic activities and the strengthening of small to medium shocks around the Heze earthquake (M=5.9) of Nov. 7, 1983 have been analysed. The result shows that the strong earthquake activities may be a precursor of a great shock in southern area of North China. It is also pointed out that the strengthening of the small to medium shocks in Liao-kao Belt may be an indication of the strong earthquake. |
