RIZNICHENKO, YURII VLADIMIRQVICH (Geophysicist) 



Yu. V. Riznichenko was born September 28, 1911. He gradu- 

 ated in 1935 from the Kiev Mining-Geological Institute. He be- 

 came professor in 1947 at the U.S.S.R. Academy of Sciences 

 Geophysical Institute where he had worked since 1938. In 1956 

 he began working at the Institute of Terrestrial Physics of the 

 U.S.S.R. Academy of Sciences. Since 1950 he has been a mem- 

 ber of the Communist Party of the Soviet Union. He was elect- 

 ed, in 1958, a Corresponding Member of the U.S.S.R. Academy 

 of Sciences. 



Riznichenko has studied the distribution of seismic waves 

 and developed seismic methods for surveying. He has worked 

 out a general kinematic method of interpreting seismic data- 

 method of the fields of time, the principles of which are set 

 forth in his work "Geometric Seismics of Layered Media" 

 (1946). Under his direction a new method of modeling seismic 

 wave processes has been established. 



Riznichenko has attended the Pugwash Conferences.
