March 12, 2014 (MCCOOK, Ill.) --
A west suburban quarry that shut down operations after an apparent small earthquake in November will resume normal operations. Hanson Materials says it will do that next Monday.
The quarry says it voluntarily suspended blasting activities following a seismic event that happened 7 seconds after a routine quarry blast.
The company says after consulting with scientists, it's believed the two events were not related.
