| Outline of Final Research Achievements |
Large-scale seismic data were obtained from seismometers located on the Moon by the NASA Apollo missions from 1969 to 1977. We developed a web system for visualizing moonquakes considering the waveform similarity to progress study of moonquake classification. Our system maps moonquakes data to two dimensional output space using Self-Organizing Map (SOM). We implemented parallel-SOM based on Hadoop and Spark as back-end of moonquake analysis. We also evaluated several features based on classified data and discovered effective features from seismic data stream. Our visualization system can help researchers of moon quake to discover new knowledge of moon.
