Dynamic behaviors of building 70 during a moderate typhoon are reproduced by processing acceleration data acquired by the vibration sensor network in Gunkanjima. Almost half of the ground supporting the building has been lost by erosion and scour in the past severe typhoon. The effects of ground vibration induced by high waves and strong winds on structural responses are investigated. Action of wave and wind on the island changes every moment during a typhoon. It is concluded that different vibrational modes of the building are excited by different load combinations of wave and wind.
