A model of the crustal structure beneath the Amami Plateau consisting of materials with compressional wavespeeds 2.0, 2.8-3.8, 5.4-5.6, and 6.7 km/sec, with thicknesses 0.3-0.7, 1.0-2.0, and 3.0-4.0 km, layered from the top, was obtained. This indicates that the 5.4-5.6 km/sec layer characterizes the structure of the plateau and implies that a wavespeed of less than 5.6 km/sec occupies more than half the crust. It is suggested, therefore, that the crustal structure is different from that of normal oceanic. The sedimentary shear wavespeed was found to be 0.39 km/sec and Poisson\u0027s ratio 0.48 from P-PS delay time produced by phase conversion at the base of the sediment. c 1983, The Seismological Society of Japan, The Volcanological Society of Japan, The Geodetic Society of Japan.
