| Abstract: | On Mar. 19, 1995,the earthquake with Ms5. 2 occurred in Nayinke township of Heshuo county,Xinjiang. Before the earthquake, the obvious anomalies had appeared in some gases dissolved in ground water in Urumqi region such as Ar,CH4,CO2 and H2S etc.,and also appeared in the fault product gas Rn in Kuerle region. These anomalies have short--impending character. This is primarily shown in two aspects: the gas content tendentiously rose in short term and jumped in impending-term. |
