Crowded streets are now empty in many parts of the world. Traffic decreased. Many people do not go out unless it is compulsory.
The coronavirus countermeasures made the world a quieter place, and silence also attracted the attention of scientists.
Seismologists worldwide now have less seismic noise; that is, it observes vibrations from cars, trains, buses and human movements, and due to the disappearance of this noise, the earth’s crust is now slightly less shaking.
According to CNN’s report, this phenomenon was first noticed by the geologist and seismologist Thomas Lecocq at the Belgian Royal Observatory.
Noise level decreased by 30-50 percent
According to Lecocq, since mid-March, seismic noise in the capital Brussels has decreased by 30-50 percent.
The closing of schools and workplaces in Belgium and the introduction of other social distance rules coincide with this date.
Thomas Lecocq says that this volume is only seen in Belgium, where everyone lives at home, in Belgium.
The reduction in sound produced an interesting result, especially in Brussels: Lecocq and other seismologists at the station began to measure vibrations that were too small for certain earthquake stations to observe.
“For example, an earthquake station in Brussels. In normal times, this is an ‘unnecessary’ station,” says Lecocq.
Earthquake stations are generally installed outside urban areas. Due to less noise from people, stations can measure small vibrations on the ground.
The station in Brussels was built more than a century ago; so before the city expands.
Due to the buzzing in the city, the station in Brussels cannot record small seismic movements. Seismologists depend on data from drilling stations.
“But the city is so quiet now that the sound level below is almost the same as the sound level below,” says Lecocq.
Seismologists in other countries also observe similar things. In London, the capital city of England, seismologist Paula Koelingijer
He published a chart in the Twickenham district indicating how much noise was reduced after the schools and social places were closed.
Celeste Labedz, a PhD student at the Califronia Institute of Technology, also included a graph in her Twitter post showing how a sharp drop in noise level was experienced in Los Angeles.
An indication of how the virus stops life Experts point out how destructive the noise is, at the same time, showing how destructive the virus has made over a million people worldwide, killing tens of thousands of people and stopping the normal rhythm of life.
According to Thomas Lecocq, these charts are an indication that people around the world comply with calls to stay at home and reduce their outside activity.
Lecocq says, “Seismologically, we can say to people: ‘Look, you feel at home alone. But, make sure everyone is at home. Everyone is doing the same thing. Everyone is following the rules,'” says Lecocq.
Raphael De Plaen, a researcher from the Universidad Nacional Autónoma of Mexico, says that this data can be used to determine the degree of compliance with isolation measures.
