With much of the world shut down due to the novel coronavirus pandemic, scientists who study earthquakes are getting a rare window into the Earth. “With COVID and people staying at home, the amount of traffic, the amount of trains, helicopters, all of that has really dropped off,” said Natural Resources Canada and University of Victoria earthquake seismologist John Cassidy. “What we’re finding is that especially in urban areas, what we call ‘background noise’ has dropped dramatically.” Reduction of seismic noise in Milano and Firenze due to the #COVID19 #lockdown(s).
