Description
The Einstein Telescope (ET) is a planned third-generation underground gravitational-wave observatory with unprecedented sensitivity. This sensitivity makes ET particularly vulnerable to environmental disturbances, especially seismic noise and the associated Newtonian noise. Characterizing anthropogenic seismic noise is therefore essential for site selection and detector design. Here, we investigate the impact of lignite mining operations in the Rhine region.
Our ongoing work combines data from temporary and permanent seismic stations in and around the mining area to study how mining-related activity contributes to the local seismic noise field. We examine spatial and temporal variations of noise levels and explore spectral and array-based analysis strategies to characterize the frequency content and propagation properties of the observed signals. The overall aim is to improve our understanding of the seismic environment associated with lignite mining in the region and its relevance for ET site evaluation and Newtonian-noise studies.
