| 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． |
| Key words: The Guanzhong region Tectonic activity Gravity field variation Maximum shear strain |
