Description
Seismic disturbances, and the resulting Newtonian noise, can arise from a variety of sources with either stationary or non-stationary characteristics. In this work, we focus on two representative transient source types: wind turbines and freight trains. As part of the integrated seismic noise monitoring and mitigation campaign at the EMR candidate site for the Einstein Telescope, surface and underground seismic stations were deployed near these sources. We first evaluate the impact of these sources at potential corner-station locations using a simple amplitude-based analysis. We then perform a more detailed study to quantify the seismic correlation between the source region and the underground observation point. These correlations are subsequently used to assess the cancellation of both seismic and Newtonian noise generated by such sources. The Newtonian-noise calculations are carried out with the pySeisNN1D numerical framework, which models Newtonian noise from localized sources in a layered medium. Cancellation performance is evaluated using classical Wiener filter theory.
