A 2.1-magnitude earthquake struck near Clarksville, Md., early Wednesday according to the United States Geological Survey.

There were no reports of damage or injuries from the quake in Howard County that occurred at around 2:10 a.m.

People took to Twitter to report they felt shaking in a broader area.

One user described thinking it was a tree crashing down.

Scientists say on average magnitude 2 and smaller earthquakes occur several hundred times a day worldwide. Tremors below 2.5 magnitude are so small that they are often not even felt, but can be recorded by seismograph.

Earthquakes in the eastern United States, although less frequent than in the west, are typically felt over a much broader region, according to USGS. A magnitude 4.0 eastern U.S. earthquake typically can be felt as far as 60 miles from where it occurred.

The Washington to Baltimore urban corridor is between more seismically active regions to the southwest and northeast, and residents of Washington or Baltimore have felt several earthquakes that caused damage in those other, more active regions.
