In order to search for a tool to test whether the earthquakes is reasonable for the design
a method based on multidimensional scaling (MDS) and the dynamic time warping distance (DTW) was proposed
which represents the dissimilarities of earthquake in a low dimensional space in a visualized way and uncovers hidden structure of earthquake. The analysis of record from the seismic array shows that the proposed method can be a powerful tool in detecting the correlation structure of spatial ground motion as well as verifying whether the algorithm is producing properly correlated motions in space.
