Short summary
Mexican seismic stations witnessed a reduction in noise level as a result of the COVID-19 lockdown strategies. The largest drop was observed in Hermosillo, which is also the city with the fastest noise-level recovery and a quick increase in confirmed COVID-19 cases. Since 1 June 2020, a traffic-light system has modulated the re-opening of economic activities for each state, which is reflected in noise levels. Noise reduction has allowed the identification and perception of smaller earthquakes.
