The vertical motion of the Medicina Radio Telescope with respect to the north-central European ”stable platform” has been determined from both VLBI and GPS with a clear tendency towards subsidence on the order of 3 to 4 mm/yr. Here, we present investigations of the local motion of the site in the context of groundwater level evolution in the southeastern Po-Plain. From levelling data which are connected to the foothills of the Apennine it appears that the subsidence is indeed closely related to groundwater withdrawal in the region.

Abstract
The vertical motion of the Medicina Radio Telescope with respect to the north-central European ”stable platform” has been determined from both VLBI and GPS with a clear tendency towards subsidence on the order of 3 to 4 mm/yr. Here, we present investigations of the local motion of the site in the context of groundwater level evolution in the southeastern Po-Plain. From levelling data which are connected to the foothills of the Apennine it appears that the subsidence is indeed closely related to groundwater withdrawal in the region.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
