SUMMARY
The COVID-19 lockdown measures in Brussels led to a significant reduction in human-induced seismic noise, decreasing by approximately one-third, as reported by a seismometer at the local observatory. This reduction has enhanced the sensitivity of the surface seismometer, making it comparable to a detector buried in a 100-meter borehole. The discussion highlights the impact of reduced human activity on seismic measurements, particularly noting that man-made noise does not significantly affect long-period seismic sensors.

I still have a large building site across the road from home that hasn't quietened down too muchTom.G said:
it's easy to see the difference between daytime … noisy and the nights ... relatively quiet
E_W short period sensor...
That's the Mw6.5 from Idaho, USA
