Around Ogaki city, by comparing clay and sand layer's distribution maps and the superior frequencies of microtremor, it was confirmed that 3Hz indicate clay layer and 2Hz indicate sand layer. In the north part of Ogaki city, a marsh occupies large area and it is divided into two parts by the WAJU-bank. In and out of the WAJU-bank, the superior frequencies of microtremor have different values and the fourier spectra have different shapes. In the east part of Ogaki city, there is a pond at a marsh reclaimed with waste. It was proved that the land has the special characteristics of vibration in array observation. In the east part of the Ibi river, the border of the Sai river's natural levee and the marsh, and the border of the Itonuki river's natural levee and fan were made clear.
