The method of AF synthetic detection on crust deformation anomaly and its application in earthquake prediction

In this paper, the unstable model of crust deformation and the anomaly F-detection are discussed. On this basis, the quantitative parameters of deformation anomaly and the detection criteria for identifying anomaly have also been given, and we detected the anomaly of simulated numerical sequences. Using the observed multi-dimension data, we computed the anomaly intensity and analyzed the possible relationship between the AF anomaly and the accumulated energy released by earthquakes. Results demonstrated that the AF index can be used to illustrate an anomaly intensity for some complicated processes and the anomaly detection has reliability and stability in some degree.
