The U.S. Geological Survey confirmed a 2.1-magnitude earthquake just north of the Moosup section of Plainfield.
The Weston Observatory at Boston College also confirmed a quake, but had it registered at 1.5.
Both said the earthquake was felt at 9:18 a.m.
The observatory said it also registered a smaller one around 9:13 a.m. That one was 0.8.
Plainfield police said they have received at least a dozen calls about them.
This comes more than a month after a series of quakes rocked the region, some with a magnitude of 3.0 and higher, according to the Weston Observatory at Boston College.
"It's kind of a loud boom and then rumbles," said Charlie St. James, who witnessed the earthquakes. "It's just something you can't forget."
He said the memories are still fresh from the series of earthquakes that happened more than a month ago.
"It kind of rattles the windows a little bit, and then you feel the whole house vibrate," St. James said.
Plainfield Police Capt. Mario Arriaga said the hundreds of phone calls the department received on Tuesday were similar to the ones they heard during the series of quakes.
"It's a routine now. They're not calling as much. There's still those that do, but I think they just need that sense of security," Arriaga said.
Police said many of the calls came from the area of Green Hollow Road, and residents said they are worried about what the earthquakes could do to the structures in that area.
"It feels like someone is underneath you, underneath the ground and they're drilling and your legs vibrate a little bit," Arriaga said.
In January, Plainfield felt several earthquakes with some registering as a 3.0-magnitude, but still not strong enough to cause major damage.
When those series of earthquakes were happening, experts from the Weston Observatory brought in portable seismographs to monitor the activity, and town officials even held a public meeting to answer questions about the unusual activity.
"I guess there's an ancient fault line that runs through the road so, you know, ancient or not, it's going to keep happening, I guess," St. James said.
Like St. James, many in the area have purchased earthquake insurance for a few hundred dollars per year.
There have been no reports of any damage or injuries from Tuesday's rumblings.
