If you thought felt a little rumble Tuesday night around dinnertime, you're not losing your mind.

An earthquake happened about 136 miles off the coast of Ocean City, Maryland last night. According to an article on Patch, the quake happened at about 6:30 PM, at a depth of 6.2 miles.

The U.S. Geological Survey measured the quake at a 4.7 magnitude, and its effects were felt as far north as Boston. It's the biggest quake to be felt in CT since 2011, when a 5.7 earthquake was felt along much of the east coast.

No damage was reported, but NBC Connecticut's Ryan Hanrahan tweeted that a small tremor was picked up at a monitoring station in Westport.
