高精度的相对和绝对重力测量定期进行。维苏威火山（意大利南部），以监测火山内部动力引起的重力场变化。此外，在Osservatorio Vesuviano（旧建筑）也有一个重力记录站，目的是以连续方式测量重力和潮汐参数的时间变化，这可能是由于火山物理状态的变化。对1994-1996年时间间隔的每小时数据集进行的分析以及与以前获得的结果的比较表明，1991年和1994年之间发生的潮汐参数发生了变化。在同一时间间隔内，在同一地区观察到约60 µGal的重力下降。与相对和绝对重力观测结果一致，自1994年以来，潮汐参数和重力残差没有发现明显的变化。
High precision relative and absolute gravity measurements are periodically carried out at Mt. Vesuvius (Southern Italy) to monitor the changes in the gravity field caused by the internal dynamics of the volcano. Moreover, a recording gravity station is also operating at the Osservatorio Vesuviano (Old Building) aimed at measuring in continuous mode the time variations of the gravity and the tidal parameters, possibly due to changes in the physical state of the volcano. The analysis carried out on an hourly data set spanning the 1994-1996 time interval and a comparison of the results with those previously obtained, exhibit a change in the tidal parameters which occurred between 1991 and 1994. A gravity decrease of about 60 µGal was observed during the same time interval in the same area. Consistent with relative and absolute gravity observations, no significant variations have been detected since 1994 in the tidal parameters and gravity residuals.
