Abstract
(English)
The results of precise levelling measurements on a specially constructed network of benchmark in the Travale geothermal area (Tuscany, Italy) revealed that the central part of this area is subsiding and that the average rate of subsidence in the period 1973-1983 was 20-25 mm/year. Three series of horizontal distance measurements were carried out (1980, 1981, 1982) to monitor variations in the coordinates of the bases of a horizontal control net. The variations noted in this interval time range between 13 and 36 mm, slinghly exceeding the semi-axis values of their error ellipses. A series of gravity measurements were carried out annually between 1979 and 1982 on a network of gravity benchmarks coinciding with part of the topographic benchmarks. The g variations observed reached a maximum of 40 µGal. A tentative correlation of these data with field exploitation data indicates a possible means of interpreting the variations observed during these surveys
