Outline of Final Research Achievements

The development of comprehensive framework to extract intrinsic physico-chemical processes hidden in multi-dimensional huge data has been conducted, by introducing the original sparse modeling techniques in the field of earth science. The research areas are the discrimination of tsunami deposits faced on the disaster prevention and the application to basic understanding in solid-earth science and geology, in order to bring fusional approach in the field of big data analysis in earth sciences. For the specific research targets, we have conducted the following three topics for the implementation of data driven analysis. 1) The application to tsunami deposits discrimination method by geochemical data analysis, 2) The risk assessment and behaviors of toxic metals in tsunami deposits, and 3) The introduction of developed sparse modeling to the soli-earth scientific problems.
