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28km,为典型的陆壳性质,上地幔40～50km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.
The meaning and equipment of the construction of the seismic station in the Natuna Islands of the South China Sea are briefly described. Using the first observation data obtained, the receiver function method and the ScS wave splitting technique are used to inverse the crust beneath Natuna Station The results show that the crustal thickness beneath Natuna Station is about 28km, which is a typical continental crust, and the upper mantle is 40 ~ 50km in low velocity.The direction of the crustal waves in Natuna is S62 ° E, consistent with the direction of crustal movement of the 巽ta block in southern Asia measured by GPS.
