For Planet Earth, 2020 was quietest period in decades


Earth had its quietest period in decades due to reduced human activity in 2020

Seismologists from 33 countries

measured a drop of up to 50% in the Earth’s ambient noise

(SOUNDBITE) (English) HEAD OF COMMUNICATION AT SWISS SEISMOLOGICAL SERVICE AT ETH ZURICH, MICHELE MARTI, SAYING: “The reason is less and less people are moving, and there was less traffic, less industries working, and you can see that in the seismic measurements. So, we see that this ambient noise had decreased."

The reduction in background noise during lockdown

resulted in the detection of small earthquakes

that would have otherwise been drowned out
