The Institute of Geophysics of the Czech Academy of Sciences, v. v. i. is one of 54 research institutes of the Academy of Sciences of the Czech Republic. Around 50 researchers are employed there, which places the Geophysical Institute among to the medium-size research institutions. It is included in the section of Earth Sciences according to its specialisation. The Geophysical Institute was incorporated into the Czechoslovak Academy of Sciences in 1953. It is a direct successor to the State Institute of Geophysics founded in 1920.

It carries out basic research into the physics of the Earth. Its main programme consists of scientific studies carried out on a regional basis, whose aim is to contribute to the elucidation of the crustal and lithosphere structure, geodynamic evolution and the physical properties of the Earth and its environment. This work is based on the study of the distribution of geophysical fields in space and time in connection with laboratory research on selected rock parametres under corresponding pressure and temperature conditions. The work of the Institute is aimed at obtaining information that can be used in prospecting, prediction and prevention of natural catastrophes and reducing their harmful impact on human beings and their activities. The institute operates several observatories (seismic, gravimetric, magnetometric, geothermal observatories).
