区域台网地震监测能力评估算法的Matlab实现

Algorithm for Assessing Earthquake Monitoring Capability of Regional Network with Matlab

采用近震震级公式方法,在已知台站噪声水平和震中距的情况下,计算出该台能记录到的最小地震震级,在震中距最近的6个台中,通过组合排序法选取布局最优的4个台进行定位,并取这4个台站中震级最大值作为最小监测能力震级,从而得到局域台网的地震监测能力。运用Matlab软件来实现该算法,并对其中的核心处理技巧进行说明。

As noise level of the station and epicentral distance are known ,magnitude of the smallest earthquake which the station can record is calculated by using magnitude formula of local earthquake .4 stations whose layout are optimal are selected from 6 stations whose epicentral distances are the nearest by combination sorting method .The maximum magnitude of these 4 stations is taken as the magnitude of the least monitoring capability ,i .e .the monitoring capability of earthquake of the local network .Algorithm is im-plemented by software of Matlab and the core processing technique is introduced .
