摘要
利用空间线性度方法,对前兆场中不同台站、不同学科的前兆观测数据从总体形态上进行综合分析,得到关于描述前兆场的新的特征量α(空间线性度)。本文给出了空间线性度的具体计算方法,并以华北地区为例,分析处理了区内1970~1994年部分地电阻率和地下水位观测资料。所得结果表明,新的前兆特征量α在中强地震之前一年左右时间内有异常显示
In this paper, the spatial linearity method had been applied to synthesitical processing of precursory data of different stations and different disciplines. The new characteristic value( α ) had been obtained that can describe all precursory field. The authors had given the formulae how to calculate spatial linearity. Furthermore, the spatial linearity method were applied to processing of geoelectrical resistivity and underground water level data from 1970 to 1994 in North China. The results show that the new characteristic value ( α ) could discriminate anomaly about one year before moderately strong earthquake.
