Characterizing the Seismic Impact of Wind Turbines on the Einstein Telescope — Marc Boxberg², Tom Niggemann¹, •Niklas Nippe¹, Achim Stahl¹, and Florian Wagner² — ¹III. Physikalisches Institut B, RWTH Aachen — ²Geophysical Imaging and Monitoring, RWTH Aachen

Knowing the seismic impact of nearby wind turbines is crucial for future gravitational wave detectors like the Einstein Telescope. In the low frequency regime, seismic and gravity gradient noise are the dominant effects impacting the sensitivity. Vibrations of nearby wind turbines are expected to be significant contributions. A deep understanding of these vibrations and the coupling into the ground are necessary to define buffer zones around the detector. I will present measurements of seismic noise at the Einstein Telescope candidate site close to Aachen and their impact on the definition of buffer zones.
