An earthquake measuring 3.6 on the Richter scale shook Washington D.C. at 5:04 a.m. Eastern this morning. While a quake of this magnitude would hardly turn heads in California, it’s the strongest to strike within 30 miles of Washington D.C. since the U.S. Geological Survey began keeping records in 1974.
Rockville, Md., was the earthquake’s epicenter. People from as far away as Pennsylvania and West Virginia reported feeling shaking. Aftershocks could occur in the next few days.
