地形变是地壳构造运动的反映,地倾斜观测是测量地形变运动的方法之一.形变与地震间的内在联系是复杂的,为探索地倾斜异常与地震的关系,现就太原台1973—1982年的资料作一分析.异常判别1.年变规律改变是六级以上地震异常一个中强地震的发生,需要有几个月甚至几年的孕震过程,形变也是由渐变到突变.太原台年周期变化比较稳定,即每年转向月份基本相同,尽管倾斜量不尽相等,但形态一样.分析比较年动态的变化,是判别中强地震震前异常的有效方法.太原台倾斜观测73、74两年向量模基本一
Terrain deformation is a reflection of the tectonic movement of the earth’s crust, which is one of the methods to measure the movement of the terrain. The intrinsic relationship between deformation and the earthquake is complex. To explore the relationship between the anomaly of the earth and the earthquake, Taiyuan Tai 1973-1982 Year data to make an analysis of abnormal 1. Discrepancy change 1. Law of change is more than six earthquakes An earthquake occurred in a moderate, need a few months or even years of seismogenic process, deformation is also a gradual change to a mutation. The annual cycle changes relatively stable, that is, the annual shift to the same month, although the amount of tilt is not equal, but the same shape.Analysis and comparison of dynamic changes in the mid-strong earthquakes is an effective method to determine anomalies before the earthquake. Taiyuan station tilt observations 73,74 Two years of basic vector mode one
