- Abstract:

Before Minle-Shandan M6.1 earthquake in 2003,short term earthquake prediction was put forward by Earthquake Administration of GanSu province on Sept.20 that about M6.1 earthquake would be occurred in middle-eastern segment of Qilian Shan Mountain,then some effective short-impending tracked measures were adopted,which gained highly appraised and commended encouragement by China Earthquake Administration,GanSu Provincial Party Committee and GanSu Provincial Government.Based on successful case predicted practice,we get various phases of prediction index system,use hierarchy analysis,ascertain early warning index system model of seismic situation in Qilian Mountain Fault.By the results of delamination of early warning model and seismic situation early warning index,we translate qualitative and quantitative objects into non-dimensional parameters of 1-4,get importance of comparing substrate two adjacent targets to a upper layer target using paired comparison,calculate cell weight vector,and check up the coherence of model's whole hierarchy.Results of this research show that the early warning value of Qilian Shan Mountain Fault before this earthquake is 3.1389; by classification standards of early warning scale,early warning lever of seismic situation is red.
