>=When finishing the Project 95-04-04 from China Seismological Bureau, a new dimension-less geoelectric precursor factor, the degree of ground resistivity anisotropy (5) was investigated and proposed. Characteristic of dynamic evolution pattern of 5 reflects seismogenic process. The ability of predicting earthquake by the method of dynamic evolution patterns of S was inspected through a statistic test which was made in big North and Northwest part of China using the method of the R value.

Characteristic of dynamic evolution pattern of 5 reflects seismogenic process. The ability of predicting earthquake by the method of dynamic evolution patterns of S was inspected through a statistic test which was made in big North and Northwest part of China using the method of the R value. The results show that more information was received from the variation of S than from that of ground resistivity. The method of dynamic evolution patterns of 5 is better than the method of ground resistivity for predicting earthquake. |
