I wonder what considerations are made to pick a location for a GW observatory. I thought that Italy is one of the most seismic active areas in Europe, and the fields around the interferometer arms seem to be used for agriculture which to me means heavy machines moving around. Why not pick some more deserted location?

Have a look at this thread when you have a moment and check out the illustration of the suspension system. There are also links there to the VIRGO website, where the illustration is from, and some background info on how the suspension system isolates the delicate parts from most of the seismic and other vibrations.

Tuscany is not a very seismic zone like Sicily or Friuli and the agricolture is mostly growing grapes for wine (Chianti, Brunello, etc). One should fear more floods from the Arno river, but they are getting rare.
