Ichiro Nakagawa (1932-2018)


Dr. Ichiro Nakagawa, Professor Emeritus of Kyoto University, passed away on April 5, 2018 at the age of 86.

Dr. Nakagawa was born on February 8, 1932, in Nara, a historical city of Japan, and graduated from Kyoto University. He was first appointed to the Disaster Prevention Research Institute in 1958, and later moved to the Faculty of Science, Kyoto University. He devoted himself to geodetic research and education, as well as a variety of laborious administration works until his retirement from Kyoto University in 1995.

In his early research career, Dr. Nakagawa carried out Earth tide observations using an Askania gravimeter during the period of the International Geophysical Year (IGY) 1957-1958. He developed a new tidal analysis method and determined the tidal parameters at 10 widely spread observation sites in Japan. This work, a part of his doctoral thesis, was a pioneering study for the later research of gravity tide profiling. Another distinct outcome from his early research was the detection of the free oscillations of the Earth, excited by the Chilean earthquake in 1960. When the earthquake occurred, he was conducting a continuous Earth tide observation at Kyoto University using the Askania gravimeter. He successfully detected the 0S2 mode with the period of 53.4 min, which was theoretically expected. Together with the other gravity observations, it was the first time in the history that the free oscillation of the Earth was observed by gravity observations. Later, his researchs were extended to establishing and enhancing the international gravity networks. He led and conducted several domestic and international gravity connection campaign measurements, for instance, a domestic campaign in 1976, along the Circum-Pacific Zone during 1979-1982, between Japan and China in 1985, and so on. He also introduced the superconducting gravimeters to Japan in late 1980s, and contributed to the establishment of GGP (the Global Geodynamic Project).

Besides his research activities, Dr. Nakagawa served as the President of the Geodetic Society of Japan (1991-1995), the Chair of the geodetic subcommittee of Science Council of Japan (1985-1991), and was chair and member of many other committees. He also devoted himself to various international endeavors. He severed as a member of the directing board of the Bureau Gravimetrique International (BGI) (1978-1991), Secretary of IAG Section III (Determination of the Gravity Field) (1983-1987), President of Section III and a member of IAG Executive Committee (1987-1991). One of his distinct achievements was the organization of the 1982 IAG assembly in Tokyo, which was the first scientific assembly of IAG. Dr. Nakagawa, as the secretary general of the local organizing committee, led the assembly really successfully, with his perfect management.

All who knew Dr. Nakagawa will remember his energetic and active personality. He was a real leader of Japanese geodesists. We never forget his achievements and respectfully mourn his passing.
