Many parts of the world will stagnate in 2020 due to the new crown pneumonia pandemic, but it offers scientists a unique opportunity to observe the impact of our humans on the planet,media reported. Among them, researchers at Imperial College London have studied the effects of the blockade on man-made earth shocks. As a result, they found what they called the longest and quietest seismic noise on record.
As population movements have decreased, carbon emissions and air pollution have declined significantly at different points in 2020, and air pollution has increased solar panel production even in some cities.
The new study focuses on seismic noise caused by the earth’s vibration. While seismic noise may come from natural phenomena such as earthquakes and volcanoes, it can also come from human activities such as tourism and industry.
The vibrations are measured by seismographs, and scientists can track the decline in man-made seismic noise by looking at data from observatories around the world. This has been the case before on holidays such as Christmas and New Year’s, but new analysis suggests that the new crown pneumonia blockade has taken the situation to a whole new level.
The data are understood to have come from 268 seismic stations in 117 different countries, and after many areas were blocked, scientists observed a significant reduction in noise from 185 seismic stations. Overall, man-made shocks fell by an average of 50 per cent between March and May this year, with the largest declines coming in densely populated urban areas such as New York and Singapore.
Dr Stephen Hicks, co-author of the study, said: “This quiet period has been the longest and greatest suppression of man-made seismic noise since we began to monitor the Earth in detail with a vast monitoring network of seismic detectors. “
In addition to new insights that lead to a significant decline in man-made seismic noise in the New Crown pandemic, it also opens up new avenues for studying human noise and natural seismic vibrations. Quiet time allows scientists to tune in to more subtle seismic signals, which in turn can be drowned out, which could signal a disaster and lead people to develop new technologies to detect early warning signals.
“The blockade caused by the new crown virus pandemic may give us a clue as to how humans and natural noise interact with Earth,” Hicks said. “
