| Abstract: | Based on the seismic premonitory information from the seismic stations and the sequence analysis of seismicityparameters of several belts in Sichuan studied areas, the data of premonitory observation and the seismicityparameters are processed firstly with the methods of normalization. Precursor and seismicity information are got.Then the canonical correlation analysis and the covariance spectral analysis are used for the comprehensive information extraction from the multi-dimension system of observation items. |
