| Abstract: | In this paper, the observation networks of precursory geosound and observation instruments are introduced first. Then it is mentioned, in particular, that audible precursory geosound was instrumentally recorded for the first time. The following section discussed the relation between the geosound and earthquake. Finally, the Nucleation time in earthquake preparation process is discussed. |
