| 摘 要： | 利用南北地震带北段及附近地区上世纪70年代以来的区域水准、跨断层短测线和90年代以来的GPS、流动重力等监测资料,结合地质构造和监测区发生的几次6级左右及以上震例,采用定性与定量相结合的方法分析研究了与地震有关的构造形变异常的基本特征及可能的机理,初步总结了基于这些不同尺度(类型)的构造形变异常进行强震中期预测的一些指标判据。

| Abstract: | 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(MS≥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. |

| Keywords: | The North segment of the south-north seismic belt of China Characteristics of deformation anomaly with strong earthquake Forecasting criterions |
