The Global Positioning System (GPS) observations defined the velocity of Nansei islands, southwest of Japan. The data showed southward motion of the Nansei islands at a rate of 1.5-2.0 cm/yr in the vicinity of Okinawa Island and 5.7 cm/yr in the Yonaguni Island. The rate is much larger in the southwestern part of the Nansei islands. The horizontal strain rate showing southwest motion was computed using the velocity of Nansei islands. Tensional strain is dominant and its axis is perpendicular to the trench axis in the south of Kyushu, vicinity of Okinawa Island, and vicinity of Ishigaki Island. However, the compressional strain is dominant and its maximum axis is oblique to the trench in the Amami-Oshima and Ishigaki-Yonaguni region.
