Results of a study of nontidal gravity variations
Abstract
Measurements of nontidal gravity variations in Eastern Europe in the period 1935-1984 are reported. It was found that the strength of the gravitational field in Siberia varied by as much as 50 mkGal in the period 1965-1977. At points in Moscow, Potsdam, and Novosibirsk, similar periodic variations were measured. The amplitude of the above variations was about 20 mkGal, and the period was about 7 years. The occurrence of variations was closely correlated with volcanic activity, and with tectonic phenomena which lead to upwelling of matter toward the earth surface. A map of the gravity variations in Eastern Europe is provided.
