Staying at home not only reduced the risk of spreading the coronavirus – it also “calmed” the earth, with a noticeable reduction in “seismic noise” – according to leading scientists.
About a third of the world’s population, more than 2 billion people, is currently in detention, staying at home or observing measures of social distancing, which means that habitual human activity has been reduced and that there has a lot less vibration shaking the earth.
Fewer trains, planes and heavy vehicles and a reduction in manufacturing and construction have all contributed to the significant reduction in vibrations felt worldwide.
The British Geological Survey’s seismology team has released a graph showing a dramatic drop in “seismic noise” recorded near Gatwick Airport, between Monday February 24, before the lockout, and Monday March 30, after their implementation
While “the earth continues to tremble”, according to the Twitter feed of the Royal Observatory of Belgium, “the movements of the ground at frequencies from 1 to 20 Hz, mainly due to human activity (cars, trains, industries, …) Are much weaker since the implementation of containment measures by the government. ”
This reduction has been most noticeable since the end of March, when home support measures were adopted, with similar findings from scientists around the world, including the United Kingdom.
About a third of the world’s population, more than 2 billion people, is currently in detention, including here in New York, which is significantly quieter than usual.

French seismologist Claudio Satriano tweeted about “spectacular noise reduction” in Paris
Satriano’s graph shows much higher noise levels in the first part of March than in the second
Speaking to Twitter, French seismologist Claudio Satriano wrote: “Dramatic reduction in seismic noise in @Paris due to # COVID19 #lockdown.
“And thank you to Parisians for staying at home! #RestezChezoi #StayHome. ‘
Meanwhile, British scientist Jessica Irving, based in the United States, published a graph showing a reduction in seismic vibration at Princeton University.

Writing on Twitter, Iriving said: ‘How does @Princeton“ sound ”differently now that everyone has to #stayathome? Here is the seismic “noise” that we record in the basement of the Guyot room. The campus is really quieter now, especially after more stringent restrictions have been put in place.
Scientists from Bern, Geneva and Zurich in Switzerland have also found a decrease in vibrations.
Frédérick Massin displayed a graph showing the vibrations before locking, after a crowd of more than 100 people and again groups of more than five people, the last showing the most spectacular reduction.
