Global quieting of high-frequency seismic noise due to COVID-19 pandemic lockdown measures

The great seismic quiet periodNoise from trains, airplanes, industrial processes, and other sources is recorded on seismometers worldwide. Disentangling this noise is important for extracting out natural signals, but the noise can also roughly track population movements. Lecocq et al. compiled seismic observations around the world and found a substantial decrease in noise resulting from…Continue Reading
