How COVID-19 has changed Earth’s movement

Cyclical variations in the Earth’s movement occur at a number of times, starting from years to decades. At every scale, cycles are caused by a number of physical mechanisms. However, while the Earth is wounded by several actions of the mankind, it has the power to emerge stronger. In continuation to that, while the Coronavirus pandemic has created a lot of havoc across the globe, it has also shown the power of nature, how it can fight all odds to strengthen itself.

The Coronavirus pandemic, right from its emergence in China has brought a huge disaster across the globe. Even as the disaster has spelled a doom for the economy, the lockdowns across countries have led to change in Earth’s atmosphere. The less noise, a few vehicles on roads and stoppage of industrial productions have made our nature a better place to live in. It has also been found that the movement of the Earth has dipped seismic noise.

According to Thomas Lecocq, a seismologist the Royal Observatory of Belgium, the  fall in noise pollution is observed only during the Christmas.  Speaking to Gizmodo, he said, “When it snows, it’s quiet, and when there’s a marathon, we can see people running”

Researchers feel that the hum of vibrations in the Earth’s crust could be because of the lesser activities of human beings and shutdown of transportations. As per them, this may help experts to check smaller tremors and also help in doing better research on volcanic and other seismic activities. It may be noted that that just as the way tremors lead our planet to move, so can vibrations, due to industrial productions and vehicle movements. While one person may not contribute much to it, many may cause noise in the background, leading to dip in a researcher’s ability to check signals that occur under same frequency.

 Those researchers who are observing the planet’s surface for vibrations have noticed fall in activity after several cities across the globe are under lockdown because of the ongoing pandemic. The British Geological Survey has collected a data through seismometers in London. The study shows fall in noise level due to less activities of human beings.

 Similar reports have also been observed from other cities across the globe like Auckland, New York and Paris.  This time however, the fall in noise pollution has taken more time than before. The measures to close, school, colleges and offices have also helped the move.

Along with the noise pollution,it is the industrial pollution that is also at the lowest level. With productions almost to standstill, the pollution has also reduced. According to a BBC report, the fall in industrial production has resulted in the dip in carbon emissions. The city like New York has reported nearly 50 percent fall in the same. China, too has reported fall of emissions to 25 percent.
