关中地区3次中小地震前后的重力变化

The change of gravity background of Guanzhong region before and after 3 medium and small earthquakes

摘要:

采用拟稳平差方法对关中地区近20 年流动重力观测资料重新进行了处理，并结合其它观测资料和研究结果，对区域内重力场变化过程、3次中小地震前后重力场变化机理、构造活动以及区内外地震间的关系等进行了较深入地分析和研究。

Abstract:

It calculated the observation data of mobile gravity in the Guanzhong region for the recent 20 years． Using the quasi-stable adjustment and other observation data and research results，we explored the variation process of regional gravity field，gravity variation characteristics in the region before and after 3 medium and small earthquakes，and tectonic activity and the relationship between earthquakes inside or outside of this region．
