Millions of people around the country will be taking part in an earthquake-preparedness drill later this morning, including those in Washington, D.C., Maryland and Virginia.
The drill is even more relevant to residents in the D.C. region, after a 5.8-magnitude earthquake centered in Mineral, Va. shook the metropolitan area in August 2011.
The quake caused damage to National Cathedral and Washington Monument, the latter of which is still closed to the public.
The drill, dubbed the "Great ShakeOut," is scheduled to begin at 10:18 a.m. Italy, Puerto Rico, Guam and British Columbia also signed up for the exercise, now in its fourth year.
