【摘要】分析研究了福建地区2001～2008年的流动重力测量资料,探讨了福建东南沿海地区重力场变化与永春ML4.6和长泰ML4.7级地震的关系。结果表明:这2次地震前,靠近震中测点的重力值有明显的变化。更多还原

【Abstract】 Based on the analysis of mobile gravity measurement data in Fujian area from 2001 to 2008,we discussed the relation between the gravity field changes in the southeast coast of Fujian and Yongchun ML4.6 earthquake on August 29,2007 and Changtai ML4.7 earthquake on July 5,2008.The results show that there were obvious gravity changes near the epicenters before the two earthquakes.更多还原
