Characterizing the Seismic Impact of Steel- and Wood-Based 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 (WTs) are expected to be significant contributions. Wood as an alternative tower material is known to decrease the transfer of vibrations into the ground for existing WTs. This talk will present measurements of seismic noise and simulations of the tower vibrations of a conventional steel-based WT and compare these to measurements and simulations of a wooden tower WT.
