WASHINGTON — A minor earthquake shook residents awake in the Washington, DC, area early Friday, rattling windows but apparently causing no serious damage.
And while residents of more quake-prone areas might scoff at the 3.6 magnitude temblor, Susan Potter, a geophysicist at the US Geological Survey, said it was the strongest to hit within 30 miles (50 kilometers) of the US capital city since they began keeping records.
The quake hit at 5:04 a.m. EST and was centered in the Rockville, Maryland, area, said Randy Baldwin, a geophysicist with Geological Survey's National Earthquake Information Center.
Baldwin said aftershocks could occur over the next couple days, but none had yet been reported. He said the aftershocks are generally of a smaller magnitude than the initial earthquake.
