06/2020-07/2020, third year at the École nationale supérieure de géologie, Nancy. She arrived in the middle of the pandemic and we only met in person a few times. Still, together with my colleagues Kurama Okubo and Eiji Yamada, we communicated every day and analysed urban seismic noise before and during the worldwide lockdowns, comparing it with mobility data provided by Google to find a link with the distance between the seismometer and the city centre. The internship went really well. Unfortunately, a paper was published in Science (Lecocq et al. 2020), so we have to focus our interpretation on the economy to submit a different paper on the same topic.
