Abstract
The gravimetric investigation of the seismoactive area in Western Bohemia started in 1991 with local experimental measurements in a small area around the principal Mariánské Lázně fault close to Nový Kostel. With respect to the aims of the study, the method was designed for complex investigations in combination with GPS measurements, hydrological and geological research starting in 1993. Precise levelling was included into the project to specify vertical displacements with high accuracy in order to eliminate their influence on gravity. Temporal changes of gravity were observed during the initial stage in 1993 - 1995.
