| 摘 要： | 简述了在南海纳土纳岛(Natuna Islands)建设地震台站的意义和设备.用获得的首批观测资料,分别采用接收函数方法和ScS波分裂技术反演了纳土纳地震台下面地壳的S波速度结构和各向异性参数.结果表明纳土纳地震台下方地壳厚度约28 km,为典型的陆壳性质,上地幔40～50 km为低速层.纳土纳的地壳快波方向为S62°E,与GPS测量的亚洲南部巽他块体的地壳运动方向一致.

| Abstract: | The building process of a new seismic station in Natuna Islands is introduced,including its significance and its infrastructure and equipment.Based on primary observation data,we use receiver function method and ScS-wave Splitting technique to inverse the S-wave velocity structure and anisotropy parameters of crust under the Natuna Station spectively.The results show that the crust beneath Natuna Station is typical continental crust of 28km thick,and there is a low velocity layer(buried depth of 40～50 km) in the upper part of the mantle.The polarization of fast wave is S62°E(North clockwise 118°),identical to that of Sundaland,Southeast Asia,determined by GPS measurements of the crustal movement. |
