UCSB's The Currrent highlighted research by Han Xiao, Zach Eilon, Chen Ji, and Toshiro Tanimoto published in Seismological Research Letters. Their research shows that existing seismic monitoring equipment in Hubei Province, China and in Italy recorded signal that describes changes in human activities as the epidemic unfolded. The authors concluded that "Seismic records provide unique signals that can elucidate human activities on a large scale". Focusing on variations in seismic noise between 1 and 40 Hz, the authors mapped in space and time the evolution of govermnent lockdowns and self-imposed behavioral alterations in response to the COVID-19 Outbreak.
