According to Xinhua news agency, with more and more countries taking measures to restrict travel, many seismologists have noticed that the background noise of the earthquake is significantly reduced, which means that the earth shaking caused by vehicles such as cars, trains, buses and airplanes and people's daily life is reduced, to a certain extent, reducing carbon emissions.
Thomas lecock, a geographer and seismologist at Belgium's Royal Observatory, seems to have first noticed the phenomenon, the Daily Mail reported on April 5. He said since the novel coronavirus transmission was carried out in Belgium in mid March, the background noise of the capital Brussels has decreased by 30%-50%. "The Earth continues to vibrate," Belgium's Wangjia observatory said on twitter, "but" the ground motion caused mainly by human activities (cars, trains, industry, etc.) is much lighter, and its impact on the environment is also reduced. ".
Other national geographers have also noticed this phenomenon. According to a chart released by an earthquake research team of the British geological survey research institute, noise levels monitored near Gatwick Airport in London have declined significantly since the UK imposed traffic restrictions. French seismologist Claudio sartriano also tweeted: "because of the new coronavirus restriction measures, the earthquake noise in Paris has been significantly reduced."
Due to the reduction of background noise, researchers were able to detect small earthquakes and other seismic events that are not easy to detect.
For ordinary people, reduced background noise may encourage them to stay at home to prevent the spread of the epidemic. Lecock said, "look! You think you're alone at home. Let's tell you that everyone is at home, everyone is the same, everyone is following the rules. "
A novel coronavirus pneumonia outbreak has estimated that more than 2 billion people worldwide are home.
