D.C. Tremor Rattles White House

A rare earthquake rumbled through Washington D.C., today, shaking windows in the White House and throughout the city but causing no major damage, according to initial news reports.

A 3.6 magnitude quake rattles D.C.

The relatively small magnitude 3.6 quake originated at 5:04 a.m., about 15 miles away in Rockville, Md. It was the largest quake to strike within 30 miles of the White House, at least since 1974, when the U.S. Geological Survey began tracking D.C. quake activity, according to spokeswoman Amy Vaughn.

ABC News correspondent John Donvan, who lives a mile from the White House, said the quake rattled windows at his home as well.
