Abstract: | Through the comparative studies of degassing activities between the eastern and the western segments, between two pull-apart regions, and between the major fault and branch fault along the north fault zone of Western Qinling (NFZWQ) in 1996 and 1997, the characteristics of degassing activities along NFZWQ were discussed in the paper.With the comparative studies of faulting and seismic activities, this paper points out the role of the degassing activity (CO2, N2, O2 and CO2/O2) in predicting and determining seismicity and faulting activity. |
