| Abstract: | Using three methods including Nakai fitting analysis,amplitude factor analysis and non-tidal fitting,on basis of deformation data,this paper analyze the relationship between deformation anomaly and earthquake in Chengde area.Through the R evaluation,reflecting earthquake capabilities of each deformation instrument of Chengde central seismostation are evaluated,the advantages and the disadvantages of the deformation anomalies in earthquake monitoring and predication are pointed out. |
