A 5.9-magnitude earthquake centered in central Virginia disrupted cell phone service and closed two nuclear reactors, numerous bridges and tunnels in East Coast cities on Tuesday afternoon.
The major wireless carriers had not confirmed the cell phone outages, but many Washington-based Twitter users said they lost cell phone service after the quake struck.
The U.S. Geological Survey said the quake struck in Mineral, Va., about 80 miles southwest of Washington, at 1:51 p.m.
The USGS said that the Tuesday quake was the largest in Virginia since a magnitude 5.9 hit Giles County in 1897 .
Two nuclear reactors were taken offline at the North Anna facility near Mineral, but no damage was reported, according to WTOP radio in Washington. Officials at the plant, run by Dominion Virginia Power, could not be reached for comment.
CNN also reported that pinnacles fell off the National Cathedral in Washington, but no tourists or other people were injured.
A Computerworld reporter based in Harrisonburg, Va., 60 miles from the epicenter, said the quake felt like a truck or school bus had hit his townhouse building, while a Computerworld editor based in the Washington suburbs of Maryland said he felt his desk shake.
Airport control towers at John F. Kennedy Airport and Newark, N.J. were evacuated along with many government and office buildings in Washington, based on reports from CNN and other sources.
The NYNEX building in New York City was also evacuated, CNBC reported.
A security camera in Parkville, Md., captured the quake and the video was posted on YouTube .
