New York City Mayor Michael Bloomberg said only two cases of minor damage were reported in all of New York City following a 5.9 scale earthquake in Virginia that rattled windows as far north as Boston.

Major river crossings are being inspected, but there are no reports of damage, he said.

“Calls to 9-1-1 and other emergency services naturally spiked, but have returned to normal,” the mayor said. “I understand from many people that this was a stressful afternoon.”

He asked property owners to inspect their properties. Both damaged buildings are in Brooklyn.

The mayor was speaking at a hastily called news conference, flanked by the police commissioner and emergency services officials.

There were no reports of injuries in the New York City area related to the earthquake.

As of 4 p.m., both major New York airports were open.

The epicenter of the quake was located about four miles southwest of Mineral, Va., which is between Richmond and Charlottesville, Va., about 80 miles south of Washington, D.C. and 340 miles south of New York City.

The earthquake was one of the largest ever recorded in the Washington, D.C., area. The quake’s depth, only 0.6 miles below the surface of the earth partly explains the widely-felt shaking, according the USGS.

In “the East Coast you have this old, hard, cold crust that does a lovely job of transmitting the waves,” said USGS Seismologist Lucy Jones.

In New York, City Hall and police headquarters were evacuated, but operations have since returned to normal.
