| Abstract: | In this paper , the effect of material migration of the underground gases on the Precursory changes was studied according to the monitoring data of the CO2, Nz, Ar and Rn from June 1993 to January 1994 before some moderately strong earthquakes in West Yunnan and nearby regions. The results show that the occurring time of the trend anomalous releasing and the short-term and imminent sudden increase of the deep-seated and the shallow origin gases is ordinal before earthquakes . The basic pattern is that the precursory anomalous changes of the deep-seated gases always occurred before, the changes of the shallow origin gasses; and this phenomenon is more visible before strong earthquakes . The author considers that the ordinal characteristics of the precursory anomalous changes of deep-seated and shallow origin gases before earthquakes is correlated with the early or late order in which the gase migrated into the ground fluid. Therefore it is important and significant to recognize this feature which is very useful for predicting the occurrence time of the coming strong earthquake. |
