EDISON - A 5.8 magnitude earthquake centered northwest of Richmond, Va., shook much of Washington, D.C. on Tuesday, and was felt all around New Jersey.

Hundreds of News 12 New Jersey viewers from Cape May County to Bergen County flocked to Facebook and Twitter to report feeling the temblor.

Officials say the earthquake was half a mile deep and centered near Louisa, Va., about 40 miles northwest of Richmond.

Major transportation facilities are up and running around the Garden State. According to a spokesperson for the Port Authority of New York and New Jersey, Newark Liberty, John F. Kennedy and LaGuardia International Airports were all briefly shut down as control towers were evacuated.

He says that planes were taking off and landing again by about 3 p.m. He also says the Port Authority's PATH trains were not affected, and that its George Washington Bridge, and Lincoln and Holland tunnels are open to traffic.

New Jersey's four nuclear plants are still operating, but are being inspected after the temblor.
