Better seismometry, Quiet Earth, Thanks Coronavirus

Data from a seismometer at the observatory show that measures to curb the spread of COVID-19 in Brussels caused human-induced seismic noise to fall by about one-third...

The facility’s surface seismometer is now almost as sensitive to small quakes and quarry blasts as a counterpart detector buried in a 100-metre borehole...

Cheers,

I still have a large building site across the road from home that hasn't quietened down too much

it's easy to see the difference between daytime … noisy and the nights ... relatively quiet

E_W short period sensor...

Man-made noise doesn't really affect the long period seismo

That's the Mw6.5 from Idaho, USA
