| Abstract: | There are 20 surveying sites crossing faults distributed along the prim block boundaries to monitor the crustal deformation.Through our analysis to these observation data,we present several judging indexes to describe the abnormal precursors of deformation curves and get some of information value about active faults.With all deformation observing data,we analyze the abnormal distribution of crustal deformation and discuss the group deformation characteristic of the faults. |
