GREAT SEISMIC GAP (M≥7) OF CHINA AND ITS DISCUSSION FOR THE USE OF THE EARTHQUAKS FORECAST OF THE MODERATE-LONG TERM |

| Abstract: | We mapped out eighteen historical great seismic gaps based on characteristic of spatial distribution of generalized pre-earthquake of China great earthquake.Studying content includes three section:The section 1 is to discuss emphatically the characteristics of great seismic gaps in continental region of China, i. e. universality of the earthquake-brewing and change of earthquake activity in gap. The relationship between seimic gap and tectonics has been discussed summarily.The section 2 is to de |
