Schools, sites closed after quake

A day after an earthquake rattled the US east coast, Washington schools remained closed and inspectors are assessing damage to national monuments.

The magnitude-5.8 quake, which some people initially feared was a terrorist attack, caused no known deaths or serious injuries.

Engineers have been studying cracks in the Washington Monument, and some federal office buildings are shut.

The quake centred on the state of Virginia but was felt widely.

It was one of the most powerful tremors to hit the US east coast since 1897.

High-rise fright

The quake shook Washington DC for about 30 seconds at lunchtime on Tuesday, with the White House, Pentagon and Capitol buildings among sites evacuated across the city.

Engineers are evaluating cracks found in the Washington Monument

In New York City, the tremor sent many people fleeing high-rises such as the Empire State Building.

"I ran down all 60 flights," accounting office worker Caitlin Trupiano said. "I wasn't waiting for the elevator."

One of the most damaged buildings in the US capital was Washington's century-old National Cathedral: three capstones broke off and cracks appeared in some walls.

Pictures posted on the cathedral's website showed the extent of the damage, including fallen statues.

"Experts are tirelessly working to assess the building damage, both structurally and aesthetically," the cathedral managers said.

At the Washington Monument, the obelisk-shaped memorial to America's first president, engineers discovered cracks in the stones at the top.

They are evaluating how to repair the monument so it can be reopened to tourists.

Just two days after the start of the academic year, 126 Washington school buildings were closed on Wednesday.

Poking fun

DC Public Schools Chancellor Kaya Henderson said the sites were being examined by structural engineers.

A handful of federal buildings were also shut on Wednesday, including some offices of the homeland security, agriculture and interior departments.

Some residents of apartments in the Washington DC suburbs were staying in shelters awaiting structural surveys at those buildings.

Two nuclear reactors were taken offline as a precaution near the epicentre of the quake, but no damage was reported.

The fuss generated by the relatively mild tremor has prompted some teasing, not least over on the west coast in California, where such events are much more common.

Images of toppled lawn chairs and wonky picture frames were posted on social networks.

The earthquake that devastated Japan in March released 60,000 times more energy than Tuesday's in the US.

It struck some 84 miles (135km) south-west of Washington, at a depth of 3.7 miles.

The epicentre was near the town of Mineral, in the state of Virginia, the US Geological Survey said.

Three aftershocks were recorded on Tuesday, measuring from 2.2 to 4.8 in magnitude.
