摘要
我国地震预报研究中的地电观测的主要特点在于有着广泛分布于各主要地震带和对国民经济有重要意义地区的固定台网,并长期连续定点地观测电阻率随时间的变化,从而在我国大陆1966年以来的地震活跃期中积累了大量与大地震发生有关的地电阻率异常变化资料。与此同时,关于地电阻率法以及它和孕震过程的关系的理论研究工作也在深入进行。本文对这些震例资料和地电阻率法理论研究进行了讨论。
The main feature of the geoelectrical observation in earthquake prediction in China is the long term of continuously observing the temporal changes in geoelectrical resistivity in the fixed monitoring networks which are popularly distributed in main seismic belts and in the regions of the economic significance in China. A lot of data of anomalous changes in geoelectrical resistivity associated with great earthquakes have been accumulated, during the seismically active periods in China mainland since 1966,which are briefly described in this paper.The theoretical study on geoeletrical resistivity method and its relation to the preparatory process of earthquake has been discussed in this paper.
