陕西地区流动重力历史资料清理分析
摘要
Abstract
The compilation process and the method of the repeated gravity historical data,as well as the standardized gravity results obtained are introduced.On this basis,the gravity field vari-ation before and after the 1998 Jingyang MS 4. 8 earthquake and the 2009 Gaoling MS 4. 4 earthquake are preliminarily analyzed and some conclusions are obtained:①the gravity varia-tion before and after the Jingyang earthquake accord with the feature that the gravity contin-uous enhancement before the earthquake and reverse recovery then;②Jingyang earthquake rupture may occur with nearby fault activities,as well as affected by the North China block stress field;③the gravity variation before and after the Gaoling earthquake is similar with the Jingyang earthquake.The two earthquakes are occurred in the Weihe fault,which are affected by the impact of the Weihe fault activity.关键词
