Columbia County residents are stumped over the origin of a mysterious series of loud, wall-rattling booms that have been shaking their eardrums -and homes- several times over the last few weeks.
Over a period of two days last week, the Columbia County Emergency Management Agency was flooded with calls with reports from residents hearing loud booms.
And as of Tuesday at 12:17 Monday afternoon, the calls poured in again.
EMA Director Pam Tucker says some callers even say their house was shook by the blast.
"Over the last 24 hours, we've had numerous reports. They come email, they call 311, they call to us, Facebook, different people," Tucker said.
Some point at quarry blasting for the noises, but Tucker says it's a state law for them to notify her of a scheduled blasting and there wasn't a demolition around the time the calls started Monday.
"We haven't been able to find anything in the areas where we're getting the reports from that would really identify, specifically, that it is tannerite being blown up or anything like that," she added.
And Columbia County isn't the only place of the hearings of unusual thunder-like noises.
