CLARKSVILLE, Md. (AP) — The U.S. Geological Survey says a small earthquake shook Howard County early Wednesday.
The quake with a preliminary magnitude of 2.1 happened around 2:10 a.m..
It was centered in Clarksville, about 15 miles southwest of Baltimore, and was about 2.1 miles (3.4 kilometers) deep.
About five hours later, the agency had received more than 300 reports through its website from people who felt the temblor across the region, including one 47 miles to the south in Charles County and another 37 miles to the northwest in Frederick County.
An earthquake with a magnitude of 2.6 struck in Woodlawn on June 25 and minor aftershock with a magnitude of 1.7 was recorded two days later.
Neither caused noteworthy damage.
