摘要
收集了该地区截止到2015年12月31日历年来具有现场调查资料的9次地震27组强震动记录和4组测震记录,同时采用EXSIM12程序模拟11组地震动记录,根据《仪器地震烈度计算暂行规程》计算了仪器烈度值,并与已有现场调查烈度进行回归分析,得到了仪器烈度和现场调查烈度之间的关系式。以2016年11月25日阿克陶M_S6. 7地震为例对这一关系式进行验证,发现换算后的仪器烈度与实际情况更为接近。
In this paper, we collected 27 strong motion records and 4 seismological records of 9 earthquakes, and adopted EXSIM12 program to get 11 strong motion records. According to Provisional rules of instrumental intensity calculation we calculated the instrumental intensity, and finally obtained the relationship between instrumental intensity and survey intensity by regression analysis. We used the relationship to convert instrumental intensity of Aktao earthquake with Ms 6.7 on November 25th, 2016, and it was closer to the survey intensity than the original instrumental intensity.
