From the article:
We humans are a rowdy, disruptive bunch. Our very day-to-day living causes the planet to hum. Quite literally - driving and travelling, digging and construction, industry, and even sports events all contribute to a constant background hum of high-frequency seismic noise.
Now, thanks to global lockdowns due to the COVID-19 pandemic, the world is experiencing the most dramatic reduction in that anthropogenic seismic noise in recorded history.
"This quiet period is likely the longest and largest dampening of human-caused seismic noise since we started monitoring the Earth in detail using vast monitoring networks of seismometers," said seismologist Stephen Hicks of Imperial College London in the UK.
