我国东北和华北地区中强地震潜在震源区的划分原则和方法

中强地震潜在震源区的不确定性，对弱地震活动区地震危险性分析结果的影响较大。因此，正确二划分中强地震潜在震源区，是地震区划加和工程场地地震安全性评价的基础。本文以东北和华北地区为例，较为系统地整理了大量基础资料，从众多典型震例分析结果中提出了该地区中强地震潜在震源区的划分原则和方法，对长春，吉林等地区进行了实验划分结果表明，本文所提出了划分原则和方法具有较好的适应性。与此同时，还对本文取得的进展和有

The Principle and Methodology of Delination of Potential Seismic Sources for Moderate Earthquakes in Northeast and North China

The uncertainty of potential sources for moderate earthquakes has greater effects on results of seismic hazard analysis in weak seismicity regions, so it is the base of seismic regionalization and seismic hazard assessment for engineering sites to delineate potential sources with moderate earthquakes correctly. In this paper as an example, the au-thers analyzed a lot of basic data systematically, suggested principle and methodology of potential sources for moderate earthquakes in Northeast and North China, basedon quite a numben of case atudies, the results show that the principle and methodology developed in this paper has batter suitablity. It is also discussed about the progress obtained in thus pa-per and put forward some issues to te furture studied.
