Subway-Induced Vibrations in Cologne Cathedral

Subway-induced vibrations significantly affect the structural integrity of Cologne Cathedral. The study found that daily subway operations generate ground motions that can be detected within the cathedral, potentially posing risks to its stability. Researchers used seismological methods to measure and analyze these vibrations, revealing their frequency and amplitude. Located near a busy train station, river, and urban infrastructure, the cathedral experiences constant anthropogenic ground motions, with subway-induced vibrations being a notable concern due to their proximity and regularity.
