20世纪90年代以来中国大陆地震Ⅵ度烈度区的分析研究
|
摘要
本文以105°E为界将中国大陆分为西部和东部,对20世纪90年代以来中国大陆102个典型震例实际调查烈度结果进行分析研究。分别研究了地震Ⅵ度烈度等震线的长轴与短轴之间、长轴与震级之间的数量关系,并给出了一定的经验相关系数;另外,还分析了地震Ⅵ度烈度区长轴方向与震中附近断层走向的一致性情况。本文的思路和结果对快速准确判断地震影响范围具有一定实际意义。
The region surrounded by seismic intensity Ⅵ isoseismal line denotes the area that the earthquake affected.Seismic intensity Ⅵ isoseismal maps of 102 earthquakes in China since 1990 are analyzed in this paper.China continent is divided into west and east areas by the line of longitude 105°E and we′ll research into the relation between the major axis and minor axis of the isoseismal maps and that between the major axis and magnitude in the two areas mentioned above.After this,we can get the experiential coefficient.Besides,the coherence of the direction between the intensity Ⅵ major axis and the nearest fault will be discussed.To a certain extent,this research is useful for fast estimation of the parameters(major axis,minor axis,direction of major axis) of the seismic intensity Ⅵ region in the earthquake emergency and response.
