The natural disaster, centered about 6.2 miles northeast of Dover, Delaware and 136 miles from New York City, occurred at 4:48 p.m., the spokeswoman said.
The quake struck at a shallow depth of 10km (6.2 miles), some 60km (37 miles) from the city of Kerman, which has a population of over 800,000, including suburbs. "I see it was felt in New York City", she said, explaining that individuals who felt the quake can file reports on the agency's website.
DE was reclassified from being a low seismic risk state to being a medium seismic risk state In 1997 by the U.S. Geological Survey and the Federal Emergency Management Agency.
Readers may recall the 2011 natural disaster that had an epicenter 38 miles northwest of Richmond.
The tremors were felt in Atlantic City, where Gino Martinelli, 67, said his house seemed to turn to rubber for about four seconds.
Carberry said there were no signs of damage at the base, and no change in operations was expected. That quake was more powerful than this one, with a magnitude of 5.8.
The USGS downgraded the quake from a 5.1 to a 4.4 on the Richter scale.
