摘要
论述了应用经验正交函数分解方法分析地壳垂直形变场 ,处理分析了甘肃河西地区的实测资料 ,结果显示 ,地壳垂直形变场的第一典型场对中强以上地震发震地点的判定有重要意义 ;而地壳垂直形变场的时间权系数能够表示区域地壳运动的相对强弱 。
In this paper, the method analyzing crustal deformation using empirical orthogonal function resolution is described. The observed data in Hexi area in Gansu Province is processed. The results show that the first prototype filed is helpful to judge the strong earthquake location. The weighted coefficients can indicate relative intensity of regional crustal related movement. It is one of the time criterions of earthquake risk assessment.
