Residents on Long Island were rattled Tuesday morning, after an earthquake sent tremors through parts of Suffolk County and the East End.

According to the U.S. Geological Survey, the 3.9 magnitude quake was felt in communities in Riverhead and as far east as Cold Spring Harbor at around 10:45 a.m. The epicenter was 79 miles southeast of Southampton at a depth of 4.1 miles, an official with the USGS said.

Some residents described the tremors as a timid rumble.

No injuries or damage were immediately reported.

Southampton Town Police Sgt. Andrew Ficurilli says the police station shook for a few seconds. He said "two or three" calls came in from town residents wondering what had happened.

The last time an earthquake shook the area was in June when a quake in Canada sent shocks down the east coast, being felt in parts all over Long Island.

This was the strongest earthquake to hit the area in 18 years. "My chair began to shake, and my desk began to shake, and I immediately knew, we're having an earthquake," said Suffolk County resident Sheila Mirjah told the PIX 11 News.

Centered off Long Island's south shore, the earthquake rattled parts of the East End and western Suffolk County. Places like Quogue and Mastic Beach. Also parts of Maryland, Connecticut and New Jersey.

"I was in the '89 Loma Prieta quake, less than 20 miles from the epicenter and um that was a very terrifying experience, and you don't forget that feeling ever" Mirjah told PIX 11 News.

And how does a 3.9 earthquake feel on Facebook, like this: Shara posted "I swear on my life that the earth Just Shook!" And her friends started commenting that they felt something amiss this morning too. On my Twitter page one follower told me "I felt it here in Jersey. Thought it was a dump truck unloading."

There were no reports of injuries or damage.
