The outbreak of the new corona virus and the unprecedented measures taken by global officials to stem the spread of the virus must have been something we have never seen before,media reported. As Nature recently highlighted, it actually brings some unexpected “side effects”. Seismologists at the Royal Observatory in Belgium have noted a decrease in seismic noise or the “buzz” of crustal vibrations since the new coronavirus control measures were introduced.
In Brussels, seismic detectors show that man-made seismic noise from moving vehicles and industrial machinery has fallen by about a third.
As “background noise” interference readings have decreased, the sensitivity of the observatory’s equipment has been improved, which helps seismologists better detect smaller earthquakes and other seismic events.
Thomas Lecocq, a seismologist at the Royal Observatory in Belgium, points out that this reduction is usually not observed until before Christmas.
