| 摘 要： | 利用福建区域GPS连续观测资料计算出应变场,由跨断层垂直形变资料计算出形变速率强度累积率,并根据跨断层、体应变等多种形变资料得到各测点压张特性的空间分布.在此基础上,研究了福建区域2005-2006年、2007-2008年、2009-2010年各时期的形变特征.研究结果表明:龙岩-厦门-东山、政海带与沙县南日岛断裂带交...

| Abstract: | Crustal strain field derived from the data from GPS observation network of Fujian area,the intensity accumulation rate of deformation velocity calculated from across fault vertical deformation and tensile or compression of each station based on across fault vertical deformation and other deformation observations are calculated, and then, based on these, the deformation characteristics in the periods:2005—2006, 2007—2008 and 2009—2010 in Fujian area are studied. It shows that there are two areas ,Xiamen Longyan Dongshan and the junction of Zhenghai and Shaxian Nanri island, with stronger tectonic activity, tendency accumulation, higher accumulation intensity, dominated mainly by compressive points, might be the zone with high risk of medium strong earthquakes. |
