大同－阳高2次地震前长治电感地应力的异常特征

Anomalous Characters of Inductive Ground Stress in Changzhi Station before and after the 2 Earthquakes at Datong-Yanggao

大同－阳高２次中强地震前，长治电感地应力曾出现明显的趋势异常和短临异常。本文就长治地应力的观测条件以及地震前后的异常特征进行了分析研究，认为对于山西地震带北部地区的地震监测预报有参考价值。

The inductive ground stress measurements in Changzhi station had showed obvious trend and short-impending anomalies before the 2 earthquakes at Datong-Yanggao. The paper analyzed the observational conditions of the ground stress in Changzhi station and the anomalous characters before and after the earthquakes,and suggested that it served the fuction of the monitoring and prediction earthquake in the north of Shanxi selsmlc zone.
