SUMMARY
The recent mine collapse in Crab Orchard, Tennessee, registered a magnitude of 3.1 and occurred on August 13, 2021, at 6:30 AM UTC. The incident took place in an extensive underground limestone mine owned by Lhoist North America, which extends approximately two miles deep with three levels. Fortunately, no injuries were reported among the workers present at the time of the collapse. This event is notable as quarry blasts typically register below magnitude 2.
