“…In contrast to the analysis by Ojeda and Ruiz (2021) for Santiago, Chile, only a few studied Mexican cities show a strong correlation of seismic noise variations and epidemiological factors (Fig. 4).…”

“…This is the scenario for Mexico City. As suggested by Díaz et al (2021) for Barcelona (Spain), Cannata et al (2021) for Sicily (Italy), and Ojeda and Ruiz (2021) for Santiago (Chile), seismic noise can be used to monitor urban mobility. However, the seismic noise levels for Mexican cities seem to be weakly modulated by the state traffic-light system.…”

“…In some countries, seismic noise levels have been strongly correlated with the lockdown phases (e.g. Díaz et al, 2021;Ojeda and Ruiz, 2021); however, in Mexico the lockdown is not imposed, and a weak correlation is observed between the noise variation and the lockdown phases. This suggests that in some cities people did not fully follow the recommendations for lockdown.…”

Abstract. The world experienced the beginning of the COVID-19 pandemic by the end of 2019 to the beginning of 2020. Governments implemented strategies to contain it, most based on lockdowns. Mexico was no exception. The lockdown was initiated in March 2020, and with it, a reduction in the seismic noise level was witnessed by the seismic stations of the national and Valley of Mexico networks. Stations located in municipalities with more than 50 000 people usually experience larger seismic noise levels at frequencies between 1 and 5 Hz, associated with human activity. The largest noise levels are recorded in Mexico City, which has the largest population in the country. The largest drop was observed in Hermosillo, Sonora; however, it was also the city with the fastest return to activities, which seems to correlate with a quick increase in confirmed COVID-19 cases. Mexico initiated a traffic-light system to modulate the re-opening of economic activities for each state. Therefore, since 1 June, noise levels have generally reflected the colour of the state traffic light. Furthermore, the reduction in the noise level at seismic stations has allowed identification of smaller earthquakes without signal processing. Also, people in cities have perceived smaller or more distant quakes.
