本文分析了内蒙古地区四个地电台站附近二十一次地震发生前后视电阻率的变化特征,并对视电阻率法预报地震的效果问题进行了讨论。尽管各台站的观测条件不尽相同,但可以看出视电阻率法对我区台站周围150公里范围内 Ms≥4.7级的地震具有一定监测能力。 This paper analyzes the change of apparent resistivity before and after the occurrence of twenty-one earthquakes near four ground stations in Inner Mongolia, and discusses the effect of the apparent resistivity method to predict the earthquake effect. Although the observation conditions at each station are different, it can be seen that the apparent resistivity method has some monitoring capability for an earthquake of Ms≥4.7 within 150 km around the station in our district.
