A 3.3-magnitude earthquake got things rumbling near Battle Creek at 11:42 this morning.
The epicenter of the quake was centered southeast of Battle Creek, about 20 miles from where a 4.2-magnitude earthquake was recorded in early May.
People across Michigan reported feeling the quake on social media.
The Calhoun County Sheriff's Department says there were no reports of damage or injuries.
Harley Benz is a scientist with the United States Geological Survey.
Benz tells us that it would be hard to describe today's quake as an aftershock of the first one.
"When we first had a reported location for this I was just assuming it was in the same spot as the one on May 2 and it wasn't," he says. "I was a little bit surprised by that."
Benz also says that earthquakes in this part of the world are pretty rare.
"We will certainly keep monitoring it and pay attention to it and if we have a few more we will start to look at this in more detail," says Benz.
