Description: 
In 1956, the Geophysics Institute was split into three institutes: 
the Institute of Physics of the Atmosphere, the Institute of Applied Geo- 
physies, and the Institute of Physics of the Earth (IFZ). IFZ now comprises 
15 departments and laboratories and employs about 100 professional research- 
ers. It is the most important Institute in the U.S.S.R. for the study of the 
history, development, and structure of the earth. The Institute sponsors 
several field explorations each year. One of these explorations in 1961 
investigated the phenomenon of uplifting on Sakhalin Island. 
At this institute, many geophysical instruments have been designed. 
Among the instruments recently developed are a capacitative receiver for 
ultrasonic pulses and a galvanometer with a period adjustable from 80 to 130 
seconds. In 1960, an investigation was carried out to check the effects of 
temperature and time on Norgard and SN-3 gravimeters. 
IFZ conducts fundamental research in seismology, gravity, terrestrial 
electricity, etc. Results of this research are applied in geophysical pro- 
specting. 
Located at the Institute is the Seismological Service of the U.S.S.R. 
ts purpose is to locate quickly the epicenters of intensive earthquakes. 
The Service gathers information from the more than 40 seismic stations under 
its control and is engaged in compiling an atlas of seismicity of the 
U.S.S.R. The central seismic station Moskva is controlled by the Department 
of Seismology, as is the Seismological Service. 
As is the case with other large institutes, the Institute’s Trudy 
is published as several different volumes. "Problems of Theoretical
