Abstract We have completed some application experiments by the MSM on Jianghan Plain and the Yangtze levee. The results show that the dispersion curve is more stable from the SPAC than the F-K method. We can get the 1-D underground structure information from several meters to hundreds of meters by transferring the size and geometry of the recording array. The 2-D and 3-D structures of the earth can be obtained by translating these results. Due to its merits of passivity, non-invasiveness and strong adaptability to the environment, the MSM has important application values in the field of earthquake engineering and engineering geophysical exploration in urban areas.
