摘要

Using the regional leveling, fault-crossing short survey since 1970s, and GPS, mobile gravitation observation data since 1990s in the north segment of the south-north seismic belt of China,  combining with geologic structure and recent earthquakes （ M_S ≥ 6. 0） in this area, the basic characteristics of structure deformation anomalies related to strong earthquakes in the area and possible mechanism are analyzed and studied in quantitative and qualitative ways. In differ scale（kind）, the strong earthquake prediction index criterions based on the structure deformation anomaly are summarized.
