A study by Greek experts on “seismic noise” has shown that
this background noise has been reduced by a factor of ten
since the imposition of the lockdown.Seismic noise is a
generic name for persistent vibrations in the ground, which
are caused by a multitude of causes, including human
activity. Professor Efthymios Sokos, from the Seismology
Laboratory of the Department of Geology of the University of
Patras, said that according to the study, the noise on the
surface of the earth during the lockdown is less than what
has been observed during a normal day in Athens.The results
revealed a decline in seismic noise levels, which began
after the first set of measures restricting activity, including
the closure of public spaces, shops and schools, with the
levels reaching their lowest when the second phase of
restrictions started.The professor explained that seismic
noise is not related to seismic activity, this means that the
reduction of seismic noise does not reduce the possibility of
an earthquake, this last ones being linked to tectonic
movement.The study also confirmed that the coronavirus
restrictions worked. The notorious decrease in seismic noise
were proof that the measures taken are effective
