DIAS seismologists detect change in “human-made seismic noise” across Ireland due to Covid-19 lockdown
Data from Dublin Institute for Advanced Studies illustrates the impact of public health restrictions on human activity
Seismologists at Dublin Institute for Advanced Studies (DIAS) have released data today (08.04.20), illustrating the dramatic decrease in human activity as a result of Covid-19 lockdown measures.
The Geophysics Section in DIAS operates the Irish National Seismic Network (INSN), with support from the Geological Survey Ireland. Instruments used by the INSN track ‘seismic noise’ – human-made ground vibrations – as well as ground motions from natural phenomena, such as earthquakes and volcanoes.
According to the data released by DIAS today, levels of seismic noise are up to three times lower now than they were before the lockdown.
Commenting today, Dr. Martin Möllhoff, Director of Seismic Networks at DIAS, said: “Our day-to-day lives result in small ground movements – for example, by cars, trains, building sites and other industries. These human-induced vibrations, called seismic noise by seismologists, vary with the human activity.
“Worldwide social restrictions due to the coronavirus pandemic affect not only levels of air pollution, but also how much the ground beneath our feet vibrates.
“With the current Covid-19 restrictions on human movement, INSN seismic noise levels have been markedly reduced. In Ireland, seismic noise levels are now up to three times lower than they were before the restrictions were introduced.”
Professor Chris Bean, Head of the Geophysics Section and Director of the School of Cosmic Physics at DIAS, said: “Such lowered seismic noise levels can enhance the capability of a seismic network to detect small earthquakes and are testament to the high levels of compliance with Covid-19 movement restrictions.”
The findings released by DIAS today mirror findings from seismologists across the world, who have been tracking how Covid-19 restrictions have impacted on levels of seismic noise.

Our second example of creativity was from our Theoretical physicists, who continued their collaborative work on complex theorems by installing some blackboards on the railings outside DIAS to work safely in the open air.

DIAS Professor @TomRayDIAS, worked on the JWST to produce the special infrared filters required by the Mid Infra-Red Instrument (MIRI), that break up the light into its various components.
JWST is now due to launch in 2021!

The provision of such a resource has never been more important to allow Celtic studies scholars continue their work during the time of COVID.
The ISOS project was launched in 1999, and since then has digitised many historical Irish manuscripts from across the world. This work continues today.
