| Abstract: | An M6.1 earthquake struck the boundary between Panzhihuan City and Huili County on 30 August 2008.Before this earthquake,the content of the escaped gas radon from ground water shows a clear change.After this earthquake we think that the content of the escaped gas radon from ground water show a middle-term abnormal,short-term and impending abnormal change.We call these abnormal changes the near earthquake hypocenter and discuss these problems. |
