The U.S. Geological Survey is reporting a 2.1 magnitude earthquake in eastern Frederick County near the Carroll County line, but area residents likely didn't even notice the minor quake.
USGS reported the earthquake happened around 6 a.m. Saturday. USGS said the epicenter was about 3 miles from Linganore, in Frederick County, and about 11 miles from Westminster in Carroll County.
Earthquakes with a magnitude of about 2.0 or less are usually called microearthquakes and are not commonly felt by people though they are recorded by instruments.
