Delaware earthquake today: magnitude 4.1 earthquake with epicenter near Dover felt in NJ, New York, Maryland, Philadelphia


A magnitude 4.1 earthquake struck Delaware on Thursday, according to the US Geological Survey. The USGS says the quake struck at 4:45 p.m. ET and was centered about 6 miles east-northeast of Dover, Delaware.

People in Baltimore, Boston, New York, New Jersey and Philadelphia felt it. The USGS says the quake was shallow – only 5 miles deep, which helps amplify its effect. There were no immediate reports of injuries or damage after the quake rocked the mid-Atlantic region of the east coast.

The Associated Press writes that downtown Dover was in turmoil as lawmakers and state house workers came out to see what had happened. Police and emergency services had no immediate reports of damage or injuries.

“I live a few miles south of Dover and my house was vibrating quite well and I could also hear the rumbling,” said the Dover police captain. Mark Hoffman said, according to CBS Philadelphia. He added that everything seems to be going well in Dover.

AP writes that Sgt. Rene Carberry, spokesperson for Dover Air Base, said people at the military installation felt it; some went out to see if anything fell. She said there was no sign of damage to the base and that there would be no change in its functioning.

CBS New York put together a few tweets in the area that confirmed residents felt the quake on Thursday:

“My house shook for about seven seconds,” said Nancy Burkley, who felt the quake in Westampton Township, New Jersey, according to CBS Philadelphia.

The station also writes that USGS geophysicist Paul Caruso says there is the potential for aftershocks.

“Aftershocks are a possibility with this earthquake,” Caruso said. “Usually the largest aftershocks we see in a series are about 1 magnitude smaller than the main quake.”

Thursday’s earthquake was initially reported to have a magnitude of 5.1 and then 4.4. Data from several monitoring stations eventually recorded the tremor at 4.1, according to the USGS.

Some may remember the mighty August 2011 earthquake that hit the east coast that rocked buildings and rocked nerves from South Carolina to Maine. The USGS said at the time that the quake recorded a magnitude of 5.8 and was centered 40 miles northwest of Richmond, Virginia.

Frightened office workers took to the streets of New York City, and parts of the White House, the Capitol and the Pentagon were evacuated.
