| Abstract: | The frequency curve with annual seqence has been drawn using the accumulated sliding value of 3 yearsas a low-pass filter,and the precursor information in the curve before every historical strong earthquakes ofGuangxi has been discussed.The conclusion that the time intervals of earthquake frequency increasing corre-spond to the strong earthquake occurring is obtained. |
