Texas isn't the only state to be hit by a rare swarm of earthquakes recently. Connecticut is also being rattled by a string of quakes.

The small town of Plainfield in the eastern part of the state experienced more than 10 in the last week - and another one this morning. The largest earthquake - a magnitude 3.1 - occurred Monday morning.

Texas town hit by 11 small earthquakes in 24 hours.

Is "fracking" to blame for earthquakes in Oklahoma?

Residents baffled by terrifying, loud booms in Oklahoma.

Its epicenter was right in resident Meredith Humphrey's backyard.

"The jolt was very loud and it was so shaky. It felt like a shock was coming up my legs and I literally fell backwards," Humphrey said. "I felt like I was struck by lightning."

She said a crack in her ceiling finally gave way during the shakes.

"Monday, I [heard] a crash," she said. "That was a lovely, dirty mess."

Geologists have descended on the area and planted sensors. They planned to meet with residents Friday to answer questions.

Last week in Irving, Texas, nearly a dozen small quakes struck in 24 hours, rattling residents.

Experts at the National Earthquake Center in Golden, Colorado, said the quakes were likely a natural fluke but they also said that huge amounts of wastewater pumped deep underground - a byproduct of both hydraulic fracturing, or "fracking," as well as other oil- and gas-extraction technologies - could also be the trigger. The Irving area has experienced oil and gas exploration.

In Plainfield, however, geologists said they were sure the temblors were not man-made.

"Plainfield has been under this glacial stress for at least 20,000 years," said Jeffrey Park, a Yale University professor of geology and geophysics. "Small earthquakes have probably been occurring maybe every 100 years. We're just feeling the latest installment."
