A geologist and seismologist named Thomas Lecocq, who works at an observatory in Brussels, Belgium, has noted the change in the vibrations he and his colleagues were recording from the Earth's surface -- saying they've reduced significantly since mid-March.

Of course, that's when most everyone else outside of China -- which was already grappling with the outbreak since at least February, if not sooner -- started implementing stay-at-home orders, quarantining guidelines, and in some cases ... nationwide mandatory lockdowns.

The Belgium study goes on to say vibrations in that immediate area caused by human activity has fallen by at least a third in recent weeks, which means people aren't driving on the roads, walking about ... or cranking their machines nearly as much as they normally do.

Needless to say, that same finding is probably being seen around other parts of the world, including here in the U.S., where we're always zooming around, especially on the coasts.

It's fascinating -- the seismologists in Brussels say the phenomenon is actually helping them pay more close attention to important stuff ... like incoming earthquakes, exact aftershock locations, oceanic noise and tectonic plate shifts they usually couldn't easily detect.
