| Abstract: | The time - spacial characteristics of modulating small earthquake and dynamic small earthquakes before and after the 12 moderate earthquakes from Mar. 3, 1995 in Xinjiang and its nearby area were discussed , when these areas seismicity were in active period. Based on the above feature , we put for-word the instable model of seismogenic system: (a) the system response model due to the modulation of external factor; (b) the system response model due to the earthquake source trigger. The results show that the swarm region and its nearby of the modulating small earthquake and dynamic small earthquakes maybe the dangerous region of moderate earthquakes in the near future. |
