- Abstract:
- In this paper,we adopt wavelet analysis method to separate different components with different wave length of gravity changes in Lanzhou-Tianshui-Wudu area from 2001 to 2006.The gravity changes were related to the recently-occurred earthquakes,such as MS5.2 Minxian Earthquake on November 2003; MS5.0 Minxian Earthquake on September 2003,MS5.0 Wudu-Wenxian Earthquake on June 2006.Then we discuss the relationship between gravity variations,earthquake activities and tectonic activities.The results show that we can distinguish different gravity changes with different wavelet components by wavelet decomposition,among which 2-order and 3-order wavelet decomposition parts can expose the middle and deep geological and tectonic activities.
