A 3.6-magnitude earthquake that startled Marylanders from their slumbers early Friday morning might have been the strongest measured tremor on record for the state.

With its epicenter near Germantown in Montgomery County, the quake was felt by as many as 3 million people in the Mid-Atlantic region, according to the United States Geological Survey.
