As a series of the previous study, intensive measurements of microtremors and S-wave velocities were made on and around the most heavily damaged areas, Shonan-cho, Hamadori-cho, and Aobacho,in Noshiro City in 1985. Results of this investigation areas follows: 1) Most of the sites undamaged by soil liquefaction have S-wave velocities above 130m/sec and the ground water level deeper than 3m below the ground surface. 2) Most of the sites damaged by soil liquefaction have S-wave velocities below 130m/sec and the ground water level within 3m below the ground surface. These sites have type a of microtremor spectra, which have peaks above 4Hz, with high probability. 3) It is found that type a of microtremor spectrum corresponds well to the liquefied sites with very shallow level of ground water below the ground surface and very small subsurface S-wave velocities. Therefore, the measurements of short-period microtremors give a high probability prediction of damage from soil liquefaction.}, pages = {64--75}, title = {秋田県能代市における地盤の振動特性(2)-1983年日本海中部地震で液状化を生じた地盤の微動特性-}, volume = {41}, year = {1988} }
