Keywords:Agricultural Facility, surface wave method, resistivity survey

To investigate underground parts of farmlands damaged by the 2016 Kumamoto Earthquake, resistivity survey, and surface wave method were conducted. The S velocity and resistivity of soil at a greenhouse where a pole of house sunk because of liquification, were high around the pole, indicating that sand derived from the lower soil layer was mixed with the silty surface soil layer.
