A seismometer is a device that’s usually used to measure earthquakes using vibrations in the earth. But recently, researchers have been using them to measure human movement. A global study shows that seismic noise is at an all time low, as a result of COVID-19 related lockdowns.

In January, there were sightings of a fireball in the sky over Southeast Michigan.

The following day, the United States Geological Survey confirmed it was a meteoroid which had exploded in the atmosphere.

At the time, the loud "boom" it caused was reported to register at 2.0 on the Richter scale, but for the USGS and NASA, it didn't seem like that big of a deal.

COLUMBUS, Ohio (AP) - Ohio Stadium is sure to be rocking on Saturday when the rival Ohio State and Michigan football teams take the field.

Geologists will find out just how much.

They've planted sensors around the stadium this year to measure the seismic activity created by fans.
