Unexplained shaking was reported from southern New Jersey up into Connecticut Thursday afternoon, and many residents went to social media to share their experience.

Some said it felt like multiple earthquakes, while others thought they seemed more like sonic booms. The first posts referencing the shaking were seen just before 1:30 p.m. local time Thursday afternoon.

"Everybody's outside right now yelling to each other about what it was ," Brigantine, New Jersey, photographer Lori Nichols told NJ.com. "Across the street, someone said their room was shaking."

According to the Earth Institute, there were at least three earthquake tremors in New Jersey, and they were gathering information from their seismometers. Nothing has been confirmed from the U.S. Geological Survey, however.

There have been no reports of damage or injuries, but the Brigantine Police Department has asked citizens to stop calling 911 in order to keep the lines open for emergencies.

Here's what some people in the area had to say as they felt the ground shaking:
