中国东南沿海形变速率异常与地震前兆关系的研究

Anomalous Deformation Rate and Its Relation to Earthquakes in the Souteast Coastal Area of China

本文用速率合成的方法对中国东南沿海地区跨断层位移测量资料进行分区合成,研究各区断层网络系统的整体活动水平与中强地震的时空演化,为该区中、短期地震趋势预测提供了可供参考的判据和指标.

Cross-fault displacement measurements were carried out in the zones of active fault mevement in order to acquire the information of ground deformation in the process of earthquake preparation,development,and occurrence.This approach may provide infor-mation of intermediate-and short-term deformation anomalies,but it is an investigation subject for seismologists to extract reliable precursory signals and reveal the intrinsic relationship between the precursory signals and earthquake process.In this paper using a data processing method for first-order difference,which has a clear physical meaning,the au-thor processes the cross-fault displacement measurements in Fujian,Guangdong,and Guangxi Provinces.
