The Mankato Department of Public Safety says a controlled blast was conducted in the Jordan Sands quarry late Tuesday morning, causing the ground to shake all across the city. Dispatch was overwhelmed with calls about a possible earthquake or explosion. City officials say that the weather may have contributed to a “pressure wave” that shook things up after the blast. Jordan Sands has suspended all blasts at this site until further notice, and the incident remains under investigation.
There were no injuries and there haven’t been any reports of damage.
Scott Sustacek, Jordan Sands CEO stated in a release that “this was routine blast that we have done many times through the normal course of our mining operation in the Jefferson Quarry, all of which have gone virtually unnoticed.” He added that company is closely reviewing the data and confirmed that the initial indication points to the incident being a ‘weather related anomaly’.
