| 摘 要： | 研究华北地区(34-42N,108-124E)地震活动的时空分布表明,不同的时期,主要的地震活动在不同的区域发生,随时空的整体性转移是明显的.太行山前断裂带是该区最重要的构造带之一,它不仅控制了其两端的地震活动,也控制了以它为界的东、西两区的地震活动.并指出,大约从19世纪以来,华北地区的地震活动主要在东区,而不在西区,地震活动格局已经发生了重大改变;作为地震预报的重点监视区,应着重考虑目前正在活动的地区,这对地震的长期预报是重要的.

THE VARIATION OF SEISMICITY PATTERN IN NORTH CHINA |

| Abstract: | By studying the temporal-spatial distribution of seismicity in North China (34-42N, 108-124 B) it clearly shows that the transfer of the main seismic activity for different areas within different periods is quite obvious. The rift belt in front of the Taihangshan Range is one of the most important tectonic zones in this region which controls not only'the seismicity of its two ends but also that of both to the east and west of the belt. It is pointed out that since about the 19th century, seismic activity was chiefly in the east. The seismicity pattern has been evidently varied. This fact may be important in monitoring areas of future occurrences of earthquakes. It is significant for long-term earthquake prediction. |
