NASA had obtained the moonquake data for about 7 years. The data is available to study the lunar internal structure and the focal mechanisms of moonquakes. Classification of sources of the deep moonquakes is one of important issues. The conventional method to classify deep moonquake sources is mutual comparison among waveforms. Recent machine learning approach enables us to improve the detection of moonquake, and classification of the sources. In this paper, we investigate the effective features to classify the moonquake sources. As a result, we showed that power spectral density of moonquake, and distance between the moon and the earth are effective features to classify the deep moonquake sources using the machine learning approach.
