According to a new study, Chelyabinsk-scale meteorite impacts happen more often than we have been aware.
The bright flare of the Russian meteor was hard to miss, and left 1,200 people injured in February 2013. What the human eye missed was two separate high-altitude explosions that occurred over Argentina and the North Atlantic Ocean just months later. That’s according to data from an infrasound network used to track nuke tests, released Tuesday by the B612 Foundation.
The data shows that there were 26 comparable events since 2000.
