D. Zavyalov, [email protected]. National Geophysical Committee RAS. Schmidt Institute of the Physics of the Earth RAS. B. Gruzinskaya, 10, Moscow, 123995, GSP-5, Russia. This report submitted to the International Association of Seismology and the Physics of the Earth’s Interior (IASPEI) of the International Union of Geodesy and Geophysics (IUGG) contains results obtained by Russian geophysicists in 2003-2006. In the report prepared for the XXV General Assembly of IUGG (Australia, Melbourne, June 28 – July 7, 2011), the results are briefly outlined of basic research in seismology, geodynamics, in the studies of physical properties of rocks as well as in some other directions. The period from 2007 to 2010 was still difficult for Russian geophysics. Owing to economic reasons scientific career is Russia is still believed to be lacking in prestige. Thus recruiting younger scientists for fundamental research in geophysics actually failed. Economic difficulties were redoubled by difficulties arising from ongoing reorganization of the Russian Academy of
