In the period 1996-2001, 41 absolute earth gravity determinations at Jozefoslaw station 6 such determinations at Lamkowko and 6 at Borowiec stations were performed. The analysis of results indicates at the station Jozefoslaw periodic changes of acceleration having one year period and 13.4+-3.0 (lambda)Gal amplitude. At the station Lamkowko and Borowiec such changes were not observed. The analysis of water relations and the results of measurements and calculations using other technologies allow us to formulate hypothesis that observed changes of gravity in Jozefoslaw are an indirect effect of atmospheric variations, namely of the magma displacements in anomalous T-T zone under the influence of atmospheric loading changes of the Earth`s crust.
