内蒙古中西部地区中小地震震源参数

FOCAL PARAMETERS OF MEDIUM AND SMALL EARTHQUAKES IN MIDWEST AREA OF INNER MONGOLIA

    摘要
  • 摘要: 依据Atkinson理论、Moya方法, 基于遗传算法, 选取呼和浩特数字台网记录的2001~2005年该区域ML≥2.5级57个地震事件, 利用ISDP软件计算了该区域的中小地震震源参数。结果表明, 参数之间存在着一定的线性关系。分析应力降与地震矩、震级之间的关系, 可初步判定内蒙古中西部地区应力降符合增加应力降模型(ISD)。

     

    Abstract: The focal parameters of 57 ML≥2.5 earthquakes recorded by Hohhot digital seismic network from 2001 to 2005 are calculated with genetic algorithm.The results show that there is a linear relation within the parameters.It can determine the stress drop model(ISD) to analyze the relation of stress drop with seismic moment and magnitude.
