Kiyoo Wadati

Wadachi Kiyoo (Japanese和 达 清 夫, transcription by JSL: Kiyoo Wadati, born September 8, 1902 in Nagoya, † January 5, 1995 in Tokyo ) was a Japanese seismologist.

Life

His grandfather was President Takayoshi today's 77 bank, a regional bank in the region of Tohoku, and Mayor of Sendai. His father died in 1922. 1925 he earned his degree from the Institute of Physics (Institute of Physics ) at the Imperial University of Tokyo.

At the Japan Meteorological Agency, he examined deep earthquakes in subduction zones (deep quakes along a shear zone, which extends to 700 km depth ). He likened the earthquake of 23 May 1925 from the January 15, 1927

Its publication in 1931 inspired Charles Francis Richter four years later to the Richter scale.

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

In 1942 he developed with Hirono Takuzo a theory of subsidence due to consolidation of mudstone.

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

According to him the Wadati - Benioff zone and the Wadati - diagram are named.

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