Shaking was felt as far north as New York City and as far south as Washington, D.C. from a preliminary magnitude 4.4 natural disaster that struck just before 5 p.m. Thursday northeast of Dover, Delaware.
Initially the U.S. Geological Survey reported the magnitude to of the quake as 5.1, before later revising it to a 4.4.
It was followed up ten minutes later by a less powerful 5.0 aftershock in the same area, the survey said.
Locally, residents from Society Hill in Lower Saucon Township to First Avenue and Spruce Street in Hellertown to Stanley Avenue in Fountain Hill were quick to post on social media that they felt what seemed to be an natural disaster.
The USGS downgraded the quake from a 5.1 to a 4.4 on the Richter scale. Thousands of people, including some on the fringes of New England, reported sensing the quake.
Some on Twitter report the natural disaster could be felt in parts of Maryland, West Virginia and Pennsylvania, too.More news: US will deport Mexican man after pier shooting

In Baltimore, the jolt was strong enough to send some people streaming out of buildings and into the streets.
Roland Balik, a spokesman for the 436th Airlift Wing at Dover Air Force Base, said he did not feel it but said people on base were talking about it.
"What we felt was kinda just a rumble, and I didn't quite know what to make of it and it was loud as well".
"I turned around and one of my co-workers was coming down the hall with the big-eyes look", he said.
Caruso said he didn't expect any significant damage, given the small size of the quake. The impact of that quake included damage to the Washington Monument and National Cathedral in Washington, both of which are still undergoing repairs.
