MONTGOMERY COUNTY, MD — A 1.8 magnitude earthquake shook parts of Maryland late Monday evening. The quake was the second to hit the state this year and the third possibly felt by residents.

According to the United States Geological Survey, the quake was centered near Spencerville in Montgomery County. It hit just before 11:30 p.m.

Since Monday's quake registered at less than 2.0 on the Richter scale, it would be classified as a microearthquake. These low-intensity quakes often aren't felt by people but are registered on seismic instruments.

According to the USGS website, the quake was also felt in Howard County and Wilmington, Delaware.

It's unclear if anyone suffered injuries in the quake.

In April, Maryland was rattled by a larger 4.8 magnitude earthquake that originated in New Jersey and shook a large portion of the East Coast. The U.S. Geological Survey said more than 42 million people might have felt the April 5 quake, centered about 45 miles west of New York City and 50 miles north of Philadelphia.

A 2.8 magnitude earthquake was also recorded in Montgomery County on Jan. 2. The quake originated about 2 miles west of Rockville, according to the USGS.
