Wadachi Kiyoo

Life

His grandfather Takayoshi was president of what is now 77 Bank , a regional bank in the Tōhoku region , and mayor of Sendai . His father died in 1922. In 1925 he graduated from the Institute of Physics at the Imperial University of Tokyo .

At the Japan Meteorological Agency he investigated deep earthquakes in subduction zones ( deep earthquakes along a shear zone that extends to a depth of 700 km). He compared the earthquake of May 23, 1925 with that of January 15, 1927.

Its 1931 publication inspired Charles Francis Richter to create the Richter Scale four years later.

In the late 1930s he became director of the Osaka District Meteorological Observatory.

In 1942 he and Hirono Takuzō developed a theory of subsidence through the consolidation of claystone.

In 1947 he became director of the Central Meteorological Observatory (English for Chūō Kishōdai) and 1956–1963 General Director of the Japan Meteorological Agency ( Kishōchō-chōkan , "head of the meteorological authority"). 1960-1962 he was president of the Japan Science Council ( Nihon Gakujutusu Kaigi ), 1966-1972 president of Saitama University ( Saitama University ) and from 1974 to 1980 of the Japan Academy ( Nippon Gakushiin ).

In 1971 Wadachi was honored as a person with special cultural merits , in 1985 he was awarded the Order of Culture .

The Wadati-Benioff zone and the Wadati diagram are named after him.

His son Miki is a physicist and professor at Tokyo University.
