A 4.1-magnitude earthquake occurred in eastern Delaware on Thursday. The epicenter of the quake was along the Delaware Bay, about 10 miles northeast of Dover, and it started at 4:47 p.m., the United States Geological Survey reported.
Tremors and aftershocks could be felt as far west as Washington D.C. and as far north as New York City and Philadelphia, reports on social media suggest. The rare East Coast earthquake hasn’t resulted in any damage or injuries. Its epicenter was near Dover Air Force base, which also said no damage was reported.
“Five seconds of house rumbling, some things shaking … then like nothing had ever happened,” a testimony from a person in Dover on the European Mediterranean Seismological Centre’s website said.

The National Weather Service’s U.S. Tsunami Warning System hasn’t reported any tsunami warning, advisory, watch or threat.
“There is no tsunami danger from this earthquake,” an alert from the center said.
Reports from people on the East Coast surfaced on social media showing the impact of the quake.
USGS Geophysicist Dale Grant told The Washington Post that an earthquake in the Dover area is “exceptionally rare.” Data from the USGS shows there have only ever been three earthquakes of a 4.0 magnitude or higher between D.C. and New York since 1950. The earthquake’s 4.1-magnitude size ties the record for largest in Delaware history, meteorologist Brad Panovich reported.
The last notable earthquake in the area was in 2011. That earthquake had a 5.8 magnitude and had its epicenter in Virginia.
