In 1991 a blind test of seismic motion prediction was carried out at Ashigara valley in western Kanagawa Prefecture, as ESG ( Effect of Surface Geology on Seismic Notion) test studies by various research teams. Predicted wave motions of the test, based on standard soil structure model, were almost satisfactory in amplitude values, but in waveforms and in spetrun characteristics they were slightly different from the observed records. After the blind prediction test, we tried to redetermine the soil structure by microtremor array analysis and to recalculate the seismic wave motions. The calculated result was well improved. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
