Task Force Pre- and post-lockdown noise levels during Covid-19 pandemic 2021

During the COVID-19 pandemic, a study was conducted to compare the seismic noise levels before and during the lockdown period. The study focused on utilizing probabilistic power spectral density as a method of comparison. Four seismic stations located in Kolkata, India; Paris, France; Berlin, Germany; and New York, USA, were chosen for the analysis.
The findings of the study revealed a significant difference in seismic noise levels between the pre-lockdown and lockdown periods. Interestingly, the magnitude of this difference varied across the selected locations. Kolkata exhibited the highest disparity in seismic noise levels, followed by Paris, Berlin, and New York, in descending order.
