摘要
本文在以往对东北地震大形势研究的背景上,基于1900年以来东北地区地震目录资料,利用多种分析方法,对该区地震活动规律及其发展趋势作了详细研究。结果认为,东北第五地震活跃期约到2008年结束,本活跃期最大地震强度为6级左右。
On the basis of analysis about great situation of NE China earthquake previously, according to the earthquake catalogue in the area since 1900, the seismicity law and developing trend have been studied in detdil by the various methods. The result suggests that 5th seismic active period of NE China will be over in about 2008, and that the maximal earthquake intensity is about magnitude 6 in this active period.
