Abstract
Abstract. Seismometers have detected the social response to lockdown measures
implemented following the onset of the COVID-19 pandemic in cities around
the world. This long-lasting pandemic has been a particular challenge in
countries such as Mexico, where the informal economy constitutes most of the
working population. This context motivated the monitoring of the mobility of
populations throughout the various phases of lockdown measures
independently of people's access to the internet and mobile technology. Here we use the variation of anthropogenic seismic noise in the city of
Querétaro (central Mexico) recorded by a network of low-cost Raspberry
Shake seismic stations to study the spatial and temporal variation of human
activity in the city throughout the pandemic and during sporting events. The
results emphasize the importance of densifying urban seismic networks and of
tracking human activities without the privacy concerns associated with
mobile technology.
