Abstract: Recordings made at five broadband seismometers, deployed in central London during the summer of 2015, reveal the wideband nature (periods, T, of between 0.01 and 100 s) of anthropogenic noise in a busy urban environment. Temporal variations of power spectral density measurements suggest transportation sources generate the majority of the noise wavefield across the entire wideband, except at the secondary microseismic peak (220 s) which are recorded across the city. We record a unique set of signals 30m above a subway (London Underground) tunnel...
