Global Positioning System (GPS) measure campaign in shear zone at low-latitudes was conducted in 1991 and 2003, for quantifying the present-day major faults' activity. The results are as follow,the north Antolia fault , Jiali fault, Sagaing fault and Sumatra fault are right lateral motion, the rates are(13.7±0. 6),(5.8±0.5) (7.1 ± 1.0) , (12.7 ±0.2) and(25. 4 ± 0. 5 ) mm/a respectively; while the Sorong fault and Guatemala fault are left lateral motion , the rates are 29.2 ±1.8),(14. 1 ±1.0) mm/a, respectively . Besides, Sumatra fault and Jiali fault also show strong squeezing, (18.5 ±1.0), (15.2±0.6) mm / a, respectively, while Sorong fault show powerful pull, reached to:(10.7±l.l) mm / a. Overall, the shear activity dominats in the shear zone at low-latitudes.%利用GPS速度研究了低纬度环球剪切带主要断裂的活动性,结果显示:北安纳托利亚断裂、北高加索断裂、嘉黎断裂、实皆断裂以及苏门答腊断裂均表现为右旋走滑特征,滑动速率分别为13.7±0.6、5.8±0.5、7.1±1.0、12.7±0.2和25.4±0.5 mm/a；索龙断裂和危地马拉断裂呈现左旋走滑特征,滑动速率分别为29.2±1.8、14.1±1.0 mm/a；嘉黎断裂和苏门答腊断裂表现出强挤压性,挤压量分别为18.5±1.0、15.2±0.6mm/a；索龙断裂表现出强拉张性,拉张量为10.7±1.1 mm/a.低纬度剪切带总体上表现出较强的活动性并以剪切活动为主.
