| Abstract: | Using Tianzhu earthquake data, the authors have analyzed the variation of frequency-spectrum structure before the Tianzhu earthquake and the aftershock by the method of the Largest entropy spectrum whose resolution is higher than the common frequency -spectrum analysis, and they try to get the geophysical information for the prediction before the earthquake. |
