Reports are coming in that an earthquake – felt just minutes ago at the North Baltimore office of The Brew – also hit the rest of Maryland as well as Washington, D.C., Philadelphia, New York, Boston and even far-away Cleveland.

(UPDATE: Besides the East Coast, tremor felt in Detroit and Indianapolis and in the Carolinas, Facebook accounts say.)

The U.S. Geological Survey said an earthquake of a 5.9 5.8 magnitude was centered near the town of Mineral, VA.

Here’s what it was like on North Calvert St., Baltimore (from M. Reutter):

“Tremor lasted at least 4 seconds, shook house (I was on second floor) and let out an odd pitched rumbling sound.

Here’s what it was like downtown (from F. Shen):

“I was at corner of Pratt and Light. Ground shook sharply for several seconds and there was a muffled boom.”

There’s no visible damage around here and, so far, no reports of damage elsewhere.

Cellphones aren’t working, and neighbors came out on the street, stunned at what happened.
