Major achievements
Dr. Hamano developed cross-disciplinary fusion research regarding the earth and planets as a single system and established JpGU as a platform for interdisciplinary research. These achievements have made remarkable contributions to the development of earth and planetary science in Japan. With regard to the internal dynamics of the Earth using geoelectromagnetism, he has made outstanding achievements in a wide range of research fields: primordial degassing models of the Earth’s atmosphere, paleomagnetism, ocean floor tectonics, convective motion in the Earth’s core, tsunami electromagnetic anomalies, and seafloor electromagnetic observations. In particular, in his research on core dynamics, he has conducted theoretical studies on the mechanism of the Earth’s magnetic field fluctuations originating from the Earth’s rotational changes, as well as paleomagnetic measurements of rocks and thermal convection experiments using liquid metals, and has developed multifaceted research on core convection phenomena. These results have greatly contributed to the development of earth and planetary science, including solid earth science.
