Combination of image-sound-vibration integrated sensing and robust data transfer is used to construct a change detection system of building group in urban areas in preparation for unexpected events. The field test under severe condition has been performed in the remote island, Gunkanjima. Nine buildings on the island are selected to monitor the long-term evolution of damage and deterioration through sensor fusion of MEMS acceleration sensor network for vibration sensing, microphone array for sound sensing and surveillance camera network for image sensing. The overall framework and current situation of the Gunkanjima monitoring are reported and future perspective is presented.
