To assess the impact of the reduction in anthropogenic activities on seismic vibrations, I researched the dates when COVID-19 lockdown measures were implemented in Canadian provinces and territories. It allowed me to generate a baseline of seismic vibrations starting a few weeks prior to the first lockdown and compare it with seismic vibrations during and after the first lockdown.

While the start of the first lockdown in Canada had a hard date, the end of the first lockdown was a soft one. Some Canadian cities extended the lockdown while others opened up with some restrictions.
