While the quake’s epicenter was approximately 83 miles SW of D.C., preliminary reports indicate that the trembler was felt as far north as New York. Reports also indicate that the ground was shaking in North Carolina.
“It’s one of the largest that we’ve had there,” USGS seismologist Lucy Jones told CNN. Aftershocks were a concern, she said. “People should be expecting (them), especially over the next hour or two,” she added.She said that she would expect to see “significant damage” to old, brick buildings near the epicenter. “If you’ve already got some damage, you might want to stay outside,” she said.
UPDATE: It is being reported that the Washington Monument has received some structural damage from the quake. From Real Clear Politics:
“The U.S. Capitol Police reports that the Washington Monument has been damaged after a 5.8 magnitude earthquake struck near the nation’s capital.
There are also reports that the Washington Monument is “tilting” from ABC News affiliate WABC.”
UPDATE: Reports now indicate that the quake has severly damage the National Cathedral in D.C.
The Washington National Cathedral, the highest building in the city, suffered damage in Tuesday’s earthquake, with three pinnacles in the central tower breaking off, a spokesman said.
