Wind generates seismic noise at Sos Enattos, Sardinia, potential site for the Einstein Telescope.

Seismic noise above 2 Hz band would interfere with the lower frequency output from 3rd generation gravitational wave interferometers.
Sos Enattos, Sardinia, is a potential site for the future Einstein Telescope, which will be built hundreds of meters underground. To characterise one aspect of the seismic field at this potential site, I examined trends in wind speed, direction, and seismic noise. Elevated seismic energy across a broad range of frequencies occurs when wind speeds are higher. At frequencies below 1 Hz, sources appear to be regional (ocean generated microseisms). At 1-50Hz, local sources dominate. Deeper, the effects of local wind-generated noise are reduced and masked by other noise sources.
